Guest Posted March 25, 2008 Report Share Posted March 25, 2008 Could be several things: One, your precat is clogged and causing that problem. Two, you running lean. Three, (and this is my guess) you have a serious problem with PB, 82....in other words, too much lead....in your foot!! Link to comment Share on other sites More sharing options...

Three, (and this is my guess) you have a serious problem with PB, 82....in other words, too much lead....in your foot!! i think running lean is the answer i have a *DM down pipe with 2.5 out the back. this car seems to go threw fuel pumps once a weak it wil be good when i put the pump in for a weak and then it wil start dying out in the high rpm band. everyoen swares its the secondery injeector but i think there 2 quick to judge. i think im gonn atake the tank downa nd wash it out . my car sat for 8 years so i think the tank has sludge in there clogging the pump.

bmwmike Posted March 26, 2008 Author Report Share Posted March 26, 2008 Still have jetvalves? still have jetvalves. how do i check vacum advance? Link to comment Share on other sites More sharing options...
chiplee Posted March 26, 2008 Report Share Posted March 26, 2008 still have jetvalves. how do i check vacum advance? seriously dude, why do you think something is wrong? the glow is normal after boosting if it's dark enough to see it. Most of us have enough ambient light around that we don't see it, even at night. If it's good and dark though, the turbo's always glowing after boost, always.

Lusion972 Posted March 26, 2008 Report Share Posted March 26, 2008 I had the same problem with my turbo, I was running to lean and when I applied to much boost it would run like horse sh_it Link to comment Share on other sites More sharing options...
jwrape Posted March 26, 2008 Report Share Posted March 26, 2008 still have jetvalves. how do i check vacum advance? Take the vacuum hose off the Vac. Adv. on the distributor, suck through the vac. line and see if you can suck through it. If you can, it's bad. If it gives resistance against you sucking on it then it's still good. Takes 10 minutes to do. Simple and easy. :biggrinumbrella1: Link to comment Share on other sites More sharing options...
Hoosierquest Posted March 26, 2008 Report Share Posted March 26, 2008 seriously dude, why do you think something is wrong? the glow is normal after boosting if it's dark enough to see it. Most of us have enough ambient light around that we don't see it, even at night. If it's good and dark though, the turbo's always glowing after boost, always. it depends. I had a daytona Z and I put the timing belt on a tooth off. the car felt doggy though it still boosted, when I stopped and popped the hood the turbo was glowing red and I dont mean just a little it was quite hot.

Force_Feed1988 Posted March 27, 2008 Report Share Posted March 27, 2008 Like chiplee said, if its dark your gonna see it glow. ESP if your running it hard! Link to comment Share on other sites More sharing options...
mikec Posted March 28, 2008 Report Share Posted March 28, 2008 After a long highway drive my 88's turbo will have a faint glow visible only at night... and it's gone after a minute or two of idling. During the day I've never been able to see the glow even after many laps at the track. If you can see the glow in the daytime, or if it looks bright (dull red=faint, pink or blood red=bright) then the car has problems (listed in order of likelyhood): * exhaust is plugged, especially the first cat conveter (aka "pre-cat") * engine is running lean which leads to excessively hot combustion. That burns pistons, cracks the exhaust manifold, and bakes the turbo. * Lousy ignition timing is leading to lean-like symptoms, detonation, etc. * engine is running very rich... raw gas is burning in the exhaust manifold and/or turbo. The water coolant line is NOT to cool the exhaust end of the turbo. All the water cooling does is keep the center section of the turbo cool enough to not bake/dry-out the oil. The early StarQuests didn't even have water cooling so having a totally dead water cooling loop will NOT lead to cherry red turbos. It can lead to premature bearing failure though as hot oil "cokes" and hardens to lumpy, hard deposits inside the turbo bearings. The eye bolts on the ends of the coolant pipes (the bolts that hold the pipes to the turbo) tend to plug up... worth checking next time the cooling system is drained. mike c.

Jehu Posted March 28, 2008 Report Share Posted March 28, 2008 (edited) My turbo was BRIGHT red when I went up to the Dragon last year. I drove it for about 2-2.5 hours (no problems) and then stopped to eat dinner. Came back out and drove it about another 45 minutes and it would not boost past 1-2 PSI. I got to the base of the Dragon and popped the hood with the car still running and it was beyond red. I let it idle until it went away. The next morning, it still wasn't boosting and the first thing we thought of was a clogged exhaust (precat or something). So I vented the down pipe (left about half an inch on the top half) and it went back to full boost. Drove it that way while I was up there (NOT recommended as it causes multiple other issues when you vent that heat in the engine bay!) and when I got back home, I gutted the precat and put it back together and she's good to go now.
