mbruneaux Posted August 29, 2015 Author Report Share Posted August 29, 2015 My oil separator is missing and after a few minutes of idling it starts to blow blue smoke a little, more likely PVC issue or valve seals? I may take the head off any way just for peace of mind. Quote Link to comment Share on other sites More sharing options...
speedyquest Posted August 29, 2015 Report Share Posted August 29, 2015 Have you done a compression test? Also how is your turbo's shaft tightness? Quote Link to comment Share on other sites More sharing options...
mbruneaux Posted August 29, 2015 Author Report Share Posted August 29, 2015 Have you done a compression test? Also how is your turbo's shaft tightness? I still have to do a compression test and I just bought another turbo that's supposed to be good to replace my cracked turbo.. Quote Link to comment Share on other sites More sharing options...
mbruneaux Posted August 29, 2015 Author Report Share Posted August 29, 2015 (edited) I feel a little better, I did a compression check and all four cylinders were at 135. The PO said he had rebuilt the engine. I also performed a leak down test and had to hold the crank with one hand while pressurizing the cylinder even to 10 PSI, I couldn't really get any audible leaks out of any of the cylinders. When I install the turbo I might just install the new Schneider springs and replace the valve seals while I'm at it. I ordered the gaskets and seals from "Dad's" I reallllllly had to fight the urge to get a bigger turbo but it would have been wrong and a waste of money since I have a million things to do and learn before I put a bigger turbo on it.

mbruneaux Posted September 5, 2015 Author Report Share Posted September 5, 2015 Found a crack on the hot side, I think i have another one in my pile of parts. That answers why I only get 7 lbs boost, I'm surprised I get any at all. Thought about it and it makes no sense for me not to have full boost with a crack on the hot side.

mbruneaux Posted September 5, 2015 Author Report Share Posted September 5, 2015 (edited) Took the old turbo off to replace it with a good unit I bought from Calquest and found much more! The exhaust manifold has a small crack in it and it doesn't appear to be leaking yet but when I took it off the head I could see how poorly it mated to the head itself. I have a good manifold and will have it relief cut and flattened. None of the studs broke off but the head is relatively new. I need a new accordion hose and will replace it with an aluminum piece and two couplers. I will be replacing all the nuts and washers as they seem to be sub par. I bought a genuine exhaust manifold gasket from Engine Machine and what a huge difference in quality with the crappy Fel-pro that was on there, I usually like Fel-pro stuff. The old turbo is toast: As you can see the fins are junk and I can feel a good amount of play on the shaft, which I think could be causing the blue smoke? Hopefully. http://i984.photobucket.com/albums/ae322/mbruneaux/Bad%20Turbo%20smaller_zpspzj2vdzz.jpg This one is better: No shaft play at all. http://i984.photobucket.com/albums/ae322/mbruneaux/New%20Turbo%20smaller_zpsgd5isbbl.jpg Edited September 5, 2015 by mbruneaux Quote Link to comment Share on other sites More sharing options...
mbruneaux Posted September 11, 2015 Author Report Share Posted September 11, 2015 (edited) Started putting it back together when I decided I might as well re-torque the head and install the Schneider valve springs I bought. Glad I did because I found this: http://i984.photobucket.com/albums/ae322/mbruneaux/4%20Cam%20lobe_zpstoveqidk.jpg The PO installed a mechanical set up and it all looks new but don't think he adjusted them correctly is my guess. The rockers are shot and many of the lobes look like they were ground down. http://i984.photobucket.com/albums/ae322/mbruneaux/4%20Rockers_zpsgtcv33jl.jpg One of the spare heads I got with the car has a complete valvetrain so I need to get it out and make sure it's good to use. I will be using this thread to see what I have... http://starquest.i-x...der=asc&start=0 After looking through the i-x site I think I really need to pull the head to see if it's a Hydraulic or Mechanical head. If I had sold this car to someone and they ran into all these problems I would have really felt bad.

One has a "zero" that might be a 6 and the other cam looks like the end with the stamp has been ground down, it's not flat like the other one. Looks like I need to buy a cam.

mbruneaux Posted September 20, 2015 Author Report Share Posted September 20, 2015 How did replacing my turbo turn into this? Head looks to be hydraulic so I'm happy. With all this off the engine I'm tempted to replace the steering box and steering coupler while I can get to it. http://i984.photobucket.com/albums/ae322/mbruneaux/Head%201_zpscrurvebj.jpg http://i984.photobucket.com/albums/ae322/mbruneaux/Head%202_zpsjogleblr.jpg Quote Link to comment Share on other sites More sharing options...
importwarrior Posted September 21, 2015 Report Share Posted September 21, 2015 if you get the head surfaced be sure to measure this before you have it machined.then be sure to grind it down back to the specs you measured before you machined it. https://youtu.be/T97Ri0ouDeU Quote Link to comment Share on other sites More sharing options...

That looks like a great mod, maybe I'll have to buy some bits and try it. Quote Link to comment Share on other sites More sharing options...
importwarrior Posted September 21, 2015 Report Share Posted September 21, 2015 not actually a mod. if you surface the head then that port should be grind down the same amount that the head was surfaced minimum.keeps the flow the same. if not then more restriction to the oil flow.

speedyquest Posted September 21, 2015 Report Share Posted September 21, 2015 I know exactly what its like when you start looking into fixing a few things and then it cascades into other parts of the car. I had the same thing happen when I upgraded to my JDL manifold and lower shores intake. I figure well heck, while I'm here... My build thread shows what happened after that lol.

speedyquest Posted September 21, 2015 Report Share Posted September 21, 2015 I guess that depends on your view of it. I look at it as a bunch more stuff to add to my To-Do list. I enjoy it.

importwarrior Posted September 22, 2015 Report Share Posted September 22, 2015 after years of owning quests i got this 89 in hopes to just drive it and make it one summer no real issues and lots of driving.WELL after 2 engines and 3 turbos and a year later i would say this year was a success compared to last year.i finally made it a summer of driving and enjoying the car. you guys amaze me with your skill and persistence on working and making these cars better.

mbruneaux Posted September 22, 2015 Author Report Share Posted September 22, 2015 So, I've come to my senses and will probably send out the head to be cleaned and checked, and remove timing chain case to inspect the chains. If I have found this many issues thus far then I need to inspect the chains as a precaution. And I could get rid of all that blue paint. I plan on removing the EGR system and following the suggestion on th 1-x site and use freeze plugs to plug the EGR holes. Anyone see issues with this? On the head, why not just save up a little more money and have bigger valves installed at this point with ARP head studs? I will more than likely replace all the chains and guides with new ones from Randy (Engine Machine Service) Things I wanted to do eventually anyway. I need to keep in mind this is a long term project....Do it right do it once. Quote Link to comment Share on other sites More sharing options...
speedyquest Posted September 23, 2015 Report Share Posted September 23, 2015 Amen brother. As far as the valves go I'd first ask what your goal for the car is. If your looking for more a budget build with around 300hp you could see more gains by spending that money in other places. If eventually you want to go full snot on it, then hell go for it. The arp head studs are something I'd always recommend. Quote Link to comment Share on other sites More sharing options...
mbruneaux Posted October 24, 2015 Author Report Share Posted October 24, 2015 Today I ordered SS valves, chains, ARP studs and gaskets from DAD and the remaining rubber hoses from RA. I'm going to try and reseal the steering box and replace the coupler this weekend and then on to the chains and head. It will take me a few months but it should be getting along fairly well. To have it running well will be huge for my morale. Quote Link to comment Share on other sites More sharing options...
importwarrior Posted October 24, 2015 Report Share Posted October 24, 2015 Sounds like a,plan. Wish I had time to get my steering box and center link in. Quote Link to comment Share on other sites More sharing options...
mbruneaux Posted October 31, 2015 Author Report Share Posted October 31, 2015 Pulled the steering box and replaced the lower two seals. I will try tomorrow to pull the steering column and replace the coupler. Then i can start putting the engine back together. Quote Link to comment Share on other sites More sharing options...
