I heard my name. Where's the beer?

 

I don't think you're allowed to ask for a beer when your name's Coke. Just sayin.

 

Rumor on the street you got some OEM pick-up o-rings.

Because I forgot to post these up before ... here's some pictures of what the engine looks like FINALLY complete. Well, almost complete, if you're a car person at all, you know these things are never complete ...

Coke's o-ring showed up in the mail (thanks Coke!), but before I went ahead and started tearing the oil pan off and all that I wanted to try re-priming the pump. So, here's what I did last Friday night. I bought the two fittings both show below. One is a just a 3" straight 1/8" NPT tube and the other a 1/8" NPT elbow fitting. (The plug is the allen head from the side of the block.)

In this picture you can see what I rigged up to try to the fill the pump with oil. I just attached a piece of plastic tubing to the threaded end of the elbow and then attached that to a funnel. What you don't see in this initial picture is that this actually didn't work. When I was forcing on the plastic tubing onto the elbow the 1/8" NPT tube twisted right out the hole in the block b/c it was only in there like 2 turns in the first place. Luckily, I had a 1/8" BST taper laying around (b/c Mitsu always uses them I keep them around) and was able to twist that right into the block. Next time I'll take a picture of that setup as well in case anyone wants to replicate it. Once I had the BST in there it worked great.

Anyway, after pouring about a 1/4 quart of oil down there and turning the car over with no injectors or spark plugs I still got no oil pressure. This gauge is threaded into the side of the block where the plug came out of.

But, here's the good news ... or the not so good news (depending on how you look at it). I think I figured out what is wrong and why I have no oil pressure.

 

THIS:

I found that in my trunk ^^^^^^^^^^ mixed in with my leftover gaskets from the Felpro gasket set on Friday night. After sitting down at the computer and searching this forum it didn't take me too long to discover that I installed the incorrect gasket on my oil pump. For those of you who may be reading this and have yet to do a G54B motor build, the gasket set comes with two gaskets - one w/ an oblong center and one with a tear drop center. The part that really pisses me off about the whole situation is that I pretty much had my FSM by my side during this whole build and this is the image found in both the 88 and 89 FSM, (I checked them both):

So, for whatever reason the image in the FSM is wrong and I need to tear the front cover off my car and replace the gasket. I'm also curious to check and make sure the little keyway didn't fall off the oil pump during install once I get in there, and, I'll obviously take a look at the pick-up tube when I'm there as well. However, at this point, I seriously doubt the pick-up tube o-ring is my issue. I already ordered replacement front cover gaskets and a spare oil pump gasket from DAD. They showed up at the house yesterday. Not looking forward to tearing this all back apart when I was so close.

 

Stay tuned. (BTW - I'm going to make a VM post about this so other novices don't make the same mistake I did)

Unfortunately they weren't very careful when they wrote the crankcase section in the FSM. They use an '83 (or non-turbo oiling) diagram. The pick up tube is a bolt on style, that bolts to the block instead of sucking from the bottom of the pump like turbo applications do.

Coke, it was actually you're response post to a Skullzaflare (I think) thread from like 2 years ago that I found when searching where I first realize this might be my problem. He did the same exact thing I did. So, you're actually helped me out twice now, you just didn't know it the 2nd time. :D

 

EDIT: If you had to put a percentage on the likelyhood of this problem what would you say?

Don't worry I made the same mistake once. And I was goin to post something about it to. I guess I should have.

 

Good to know I'm not the only one! Maybe this year I can actually make it to the StarquestJoe meet w/ a Starquest ... that would be a first.

Alright .... drum roll please ..... we are up and running ..... yeah!!!

 

I didn't take any pictures of the tear down b/c, well, we all know what a Starquest looks like coming apart. I just drained the coolant and oil. Removed the radiator, took off alternator, p/s pump and other misc things in the way and then the water pump. I got lucky, I was able to remove the front cover fairly easily without damaging the headgasket, which is what I was most worried about. I think the fact that the motor only had about 30 secs worth of run time really helped me out.

 

First picture I took was of the sump. In my hand is Coke's new o-ring and the one that was installed. I didn't seem like there was a probably with the o-ring or the way the sump was seated, but I replaced it with the newer one anyway since I was already tore down that far.

 

PICK-UP AND O-RiNG:

Next I took off the oil pump, checked for the woodruff key, which was in fact there, and then opened it up to make sure everything was OK inside.

 

OIL PUMP INTERNALS:

I packed the lower triangular space you see above w/ Vaseline, and then I also added Brad Penn through the oiling journal after I reinstalled it onto the block.

 

Of course, the whole reason I tore this all apart was to install the correct gasket. Here's the wrong gasket and a new teardrop (correct) gasket from DAD.

Here's the oil pump reinstalled to the block w/ the new gasket behind it.

In the final picture here, the car is completely back together and running. If you look at the fuel pressure gauge closely you can tell the car is running b/c there's pressure on the gauge.

Plenty of oil pressure, and best of all ..... NO tapping in the head. Actually, the motor sounds really good so far. As far as "driving" goes, I reversed it out the garage and pulled it back in, in 1st gear. This is a new transmission for this car, and I know nothing about it's history other than that it only has 58k on it. So far so good, we'll see how the other gears are on the road. In order to go for a test on the street I'm going to have to completely overhaul the brakes. Sitting outside for 18 months while I built this motor did a number on them. The car no longer rolls the rust and corrosion is so bad. So, I have some work to do yet. Provided I can get that all fixed up, I'll still need to get it inspected, but that shouldn't be a problem.

 

I made leaps and bounds of progress yesterday, just got a little bit more to go......

hard to believe that one little missing hole in the gasket would cause so much trouble - damage.

glad to see you got it resolved.

 

Tell me about it.

 

Hopefully no damage ... we'll see about that once we get er road worthy.

So, I know these cars are notorious for their front bumpers rotting out ... mine was no different. After taking it all apart I realized just how scary it really was, but, it's the only one I got for now (other than the one on my Starion that's staying on that car). I started with a whizzer and cut away all the rusty parts of the bumper that were just too far gone to save and tried to leave it with some structural integrity. Then, in an attempted to prevent it from getting any worse (for now) I hit it up with some brush on rustoleum. Here's what I did Friday morning:

Even though I know it's not pretty, I think it came out pretty good.

Now that I got the bumper finished up, it's time to mount the front of the car back up. It was a total bear getting the front urethane cover back onto the bumper, not looking forward to doing that again on my other car.

Next, I mounted the front air dam back up. I have a NOS one in my garage (no, it's not for sale :D), but I decided to mount the beat-up one back on for now till I decide the future of this car. I did find these really sweat 10mm flange nuts laying around in my garage that made mounting it all back together way easier than the setup from Mitsu.

If I end up keeping this body down the road, I'll probably end up eventually replacing the front end or having it all painted, it's pretty rough. Right now, my main focus was to get the engine running and looking sweet. I'll worry about the rest later.

 

About all I have left to do is a brake overhaul, get it inspected, and start working on a motor break-in ...... very, very close.

I spent this afternoon and evening taking a look at the brake situation going on with this thing. Unfortunately, 3 out of the 4 caliper pistons are seized. I knew it wasn't rolling well, and I knew there were some issues, but I didn't think it was this bad. The front drivers side is the only one that works. The rear drivers side we actually had to cut the top caliper bolt off b/c it was seized in place. Even tried heating it with a torch. Seized.

 

So, I guess I'm going to do some research on RockAuto and I'll placing an order very shortly. Any advice on brands, rebuild kits, whole assemblies, what to get, what not to get? Thanks.

 

About, the only thing I really accomplished tonight was getting black plastic grill mounted ... lol.

Looks like the Centric's on RockAuto are cheapest by a few dollars. Anybody buy them and have good success with them? Says they are re-manufactured so I can't see how they'd be any different than other of the other re-manufactured ones ... problem is they are out of stock. They show at Rockauto, but when you go to place them in your in-bin it says they aren't available. Might have to rebuild them myself .... Edited by techboy

Youll have to ask importwarrior since i got my calipers from him, but the ones i got had the mounting tabs (?) too short. The front ones; ended up using the old ones. Not big of a deal. The calipers where exactly the same and worked fine. Just a heads up on what you might end up getting. You know how it is with these cars

Haven't had too much time to dedicate to the car lately since hitting a wall with the brake situation, but I did manage to get my exhaust fixed up. I had two mufflers laying around that were both bad, so I had a local weld shop make them into one. Did a real nice job. I'm pleased. I also polished up the aluminum tips with some Mothers.

Brief Update - the new-old stock exhuast is hanging on the car, and I reworked the battery terminals with new connecting posts b/c they were making lousy contact last time I worked on the car.

 

As far the brakes go .... I managed to track down (with a heads-up from tsi-tom) a very nice condition set from the F/S forum here on the board. Thank you Eduardo! The old brakes have been completely removed from the car. So, whenever I next get a good chuck of time I should be able to mount these up, bleed everything out and take her for the maiden voyage. Crossing my fingers it performs under actual load as well it's been sounding just driving in and out of the garage ...
