My 94 BPU Supra tt has been leaking oil for a few months now. At first I thought it was the rear seal taking a dump on me. After reading several threads in this section I have come to realize that it is the valve cover gaskets. I have the classic oil on the sparkplugs ect... I am thinking while I have the valve covers off that I will polish them. They are aluminium right??? I have seen this done, but have never heard anybody talk about doing it. Also my dumb ass have neglected to purchase a toyota service manual... so is the valve cover bolt torque rating 48in/lbs???

Thank you
Brandon

Hey, I believe that they are aluminum. I just got done polishing my stock intake piping and intercooler piping and the valve covers were next on my list too. I can't help you on the torque, but if you contacted Curt Aigner or looked on MKIV.com, they usually have the torque settings for everything if nobody else chimes in.

48in/lbs sounds right. I just put mine on the other day. I just used a 1/4" drive and just snugged them up. You will also probably need to get another set of the grommits that the bolts go through too.

Yes the valve covers are aluminum. My roomate polished mine and the look bad-a$$!

Good Luck,

Shane

Do you put gasket sealer or any other special stuff on there? So to replace them you need 2 gaskets and all the grommits around the bolts? I need to do mine

it wouldn't hurt to put a little bit of grey silicone in the 4 corners of the head where the gasket will meet. just a little insurance against leakage.

I never put any sealent on my valve cover gaskets, it might not be a bad idea but I have never done it personally..

2 Gaskets and all of the bolt grommits. You might want to also check the rubber hoses that connect the 2 valve-covers together( above the spark plugs.) Mine were old and crumbled when I removed them, so I had to order new ones.
Good Luck,

i agree, it's not required but some people end up having leaks in those areas again after replacing the gaskets, so it's just cheap insurance. i've done it both ways and i haven't seen them leak.
