Indeed, and over tightening can ruin a good seal. The torque spec is 23 INCH lbs... NOT ft lbs. Hand tight is pretty much it; Hence the philips screws versus bolts.

Well I tightened them down as tight as I could by hand. I got up in the engine bay to make it easier. Do you think I may have over tightened the valve covers

Well, it's hard to crush new seals by overtighteing by hand with a screwdriver... How old are the seals? They may have cracked or they may be compressed from age (they may still be very flexible in this case, that doesn't mean they're still good).

Sorry its been so long sence i posted anything iv had some crazy things happen in the past 2 weeks. i have moved to a new living place twice within this time.

My baby is officialy leagal and back on the road with a few minor problems ill address in another post for now ill post some pics that i forgot to post.

Heres my masking job before i painted the manifold with some high heat paint.

ok so the car is running now and im having a few problems.

1. Its a little hesatent to start and when it does it bogs the check engine light comes on and the rpms fluctuate at like 500 to 1000 untill i push the gas. It levels out to 1500 after i rev it once the engine light also turns off. (boost or vacume leak maybe?)

2. Theres this really weird sloshing noise I hear ever once and awhile it sounds like its in the dash or right infront of it. I was thinking it may be the heater or something, but im not sure.

3.When i start the car the oil pressure is high. is this normal? after it gets warm its below 40 untill i push the gass but when i start it up the pressure is way above 40.

4.when the turbo starts to boost it feels like im getting more acceleration when im not flooring the car like maybe the actuator is releasing the pressure but the psi gague says its pushing 8psi but it pulls harder around 5 or 6. (boost leak again???) and it takes it abit to rev out to 6k rpm its hard to explain. its like its not getting the full 8psi or not getting enough fuel or something. maybe the afm is dirty im pretty lost on this one.

5. after full throtel boosting the car sometimes dies or it will bog and the check engine light will come on but if i hit the gass it levels out again like it does when i first start it up.

6.Is it normal for all the TEMS lights to come on when i have it in normal mode? all three come on from time to time in normal mode under normal driving condiions no hard acceleration or anything.

if anyone can help me with this i would be very greatfull.

thanks for reading my thread and helping with my noobyness : )

ohh and i have come to understand that supras are sexy as hell and verry ammusing to drive : )

your pressure should not go above 40, get a real oil pressure diagnostic gauge and see whats the real numbers are before we proceed. in the mean time consult the tsrm for possible issues.

Do not, I repeate DO NOT! try and clean your afm with some sort of solvent.

Yep! road conditions, braking, anything really will make your Tems light fluctuate, completely normal.

for the things that I didn't answer give them a search here with my name in it or cre's is always a safe bet. im about to walk out the door so im a tad rushed. Ill get back to you tonight.

Hey man i just got a 89 supra turbo, and quickly learned, they all blow the headgaskets, eventually. well if its a 7m motor. defect from factory. If you are hearing a sloshing or girgglely noise behind the dash, thats one of the signs. mine kept blowing antifreeze out of the overflow, i pressure tested the system, it all checked out. eventually it went way bad, im in the process of replacing it right now, i think that the car will be awesome. eventually, right now i dont wanna look at it!
