Just getting started , a few questions
 

Hi all! I just purchased a 1986 Toyota Supra, my first ever. Car has some miles on it but I have all the maint. records from the car and the body is not in bad shape. I am just starting to put together a list of things that I need to work on mechaniclly with the car. The first problem I want to try and fix is that the heater blows hot air all the time! The blower speed adjustment seems to work fine, but the heater seems to always be blowing out hot air. Where do you think I should start with diagnoseing this prob? The kid that owned the car before me put on an aftermarket muffler, so I would like to replace that also, kinda loud for an older guy like me. Thanks for any help and I am looking foreward to getting into this car, I always wanted one, I already took my 77 year old mom for a ride and she loved it!! :bouncy:

Hiya! and welcome to the forum!

First off, this isn't the section you want to post this, let me know which generation this is and I'll move it to the correct section. Is this a '86 or a '86.5? (86.5 has the 7M).

Hmmm, Sorry Cre, All I can tell you is that my car has the 2.8 motor in it, not the 3.0, does that help? Sorry, I am still learning!

Woops, sorry!
 

Hey Cre, I tried sending you a pm, but it said you don't allow those. I am not sure what a 7m is? All I can tell you is that I have the 2.8 L motor. Thanks.

2.8L is the 5MGE, 3.0L is the 7MGE (or 7MGTE if it's turbocharged). Since yours is a 2.8L 5MGE, you have an early 86 (MKII) Supra, and I'll move this to the appropriate forum

Blown HG , what else would you check?
 

O.k. So it turns out I have a blown head gasket on my 86 Supra. Blown between 2 and 4, and 5 and 6 cylinders. Sent head out to be checked for warpage. What else would you do now that I have the head off the car? I had an oil leak that I am still not sure what the source was. Maybe the HG was causing that. The car has 157000 miles on it. Thanks for any suggestions.

what i would do, if clean the block surface as good as you can with some break cleaner (gunk) and make sure that surface is too good to eat off of...
also clean up anything you would not be able to reach with the head on...

it all depends on what YOU want to do with the car.


also that oil leak may have been a hg or it may not have been.
most common spot if the cam towers my friends went about a month ago...
also heard if you dont rtv your cam towers WITH new gasket there gona leak...

another possiblity is just your valve covers, obviously there removed, just grab some gaskets for them also and rtv them up aswell!

make sure to use a good heat rated rtv or other on all your engine component...

Thanks canadian, that helps. I am assumeing that rtv is a sealant product? Can I find it at any automotive parts store? I am checking into the cam towers next.

New valve cover gaskets are rubber and should not get RTV
For cam tower gaskets (metal) use that copper spray stuff

meh i would still rtv the bolt gaskets, they still always seem to leak
