1985 P-type 6mge rebuild/mods

[MrBubbles00482]

Well not much progress the past day or so, working on getting my garage door springs hooked up which it should be done in the morning.

Tomorrow I'm: Pulling the head, exhaust manifold, disconnecting main fuel bracket from block, disconnecting clutch release cylinder, back up lights plug, pretty much getting it ready to pull friday minus the drive shaft (which I might go ahead and get out as the swing bearing needs replacing)

BUT, here are some pics to entertain. What I'm dealing with as far as cleaning. Keep in mind this is just outside work, everything will be hot tanked to clean the rust/impurities from the inside before paint.

Block and head will be a similar color to the rear thermo housing color (lightish silver) unless I get frisky at the paint store and go crazy....Ford blue anyone? lol
Head will be silver, valve covers matching blue to the car, Lower intake silver, upper matching blue, raised portion on the valve covers and upper intake will be sanded and polished. New alt will be installed, power steering will be cleaned and resevior polished, AC compressor will just be cleaned.

Rear thermo housing wire wheeled next the the thermostat cover.


Both wire wheeled next the lower intake....lol.....

sorry cant really give advice on the valve question, but i am impressed with your level of tenacity! im kind of inspired to jump into my car as you have yours.. although here in WI we still have freezing temperatures and a lot of snow on the ground... so i will be waiting.. but nonetheless keep up the good work!

Thanks man, I've about got the garage door hooked up on my dads shop. It's an old 80's early 90's flat door that pushes out and slides up with the help of springs, so it's a pain in the ass to get adjusted and what not.

On the intake and other pieces I'm just going to take them to the machine shop and get them hot tanked. With stuff like that I'd just rather pay to have them cleaned then take more time. I have no transportation as my 92 cutlass dropped a valve last week so this is a quick ordeal.

Thanks bro! And go for it! Just be patient and remember the service manual is your friend. I'm 20 years old and have learned everything I know from reading on line/forums and trial and error. Just be patient and very thorough and you should be fine.

Okay, I need some advice.

I have the head coming off this afternoon, and I'll be taking it to the machine shop shortly. Going to go ahead and replace valve seals and springs.

Question is, replace valves? I can get OE valve from rock auto for 100$ for a set of 12. What about going with rabid chimp oversized valves? Setup will be full CAI, stock manifold (unless I can afford a header), 2.5 manifold back into a magnaflow.

I've talked to a few people and they said I won't see any gain unless I port and polish the head and intake.

Any input would be great. My budget has expanded a little bit so I'm looking into more motor mods I can do staying NA.

Just a good feeling to seeing another Supra getting back on the streets! Do you think you are going to be able port/polish the head? I personally would get the 1mm oversized valves if you do, you may want some boost a few years from now, then you can do the manifold if you are, and no need to take off the head now! We don't have the heads those lucky 7M guys do. They try not to rub in the fact of twice the valves, but I know what the're thinking... J/K Subscribed!

I'm not going to port and polish the head or do oversized valves. I plan to boost later on, but it will be with forged low compression pistons and 15+ psi, so the motor will be out again.

I got the head off. Cylinders 4 and 5 are letting oil through, the exhaust manifold is covered on the inside. All the others seem fine. As far as the head, the exhaust valves are toast (or it seems) and the intake aren't THAT bad, but I'll be doing new OE valves, stem seals, and springs.

As far as the cylinders, the wear isn't bad. Hopefully I won't have to get new pistons and I can just get new rings and have everything cleaned.
Pictures up in a little bit, possibly about to pull the motor.

Wow had no idea your future turbo setup would have that much boost, then it would make sense to hold off for now, work some bugs out, you wouldn't wanna drive around with a low comp engine and no turbo! Whatever path for now, I know how much it sucks to have your backup car take a crap, then pressures you into rushing the build, or fixing the broken parts, so keep that in mind, and stay meticulous! Your polished parts are night and day. That engine will pay you back.

[MrBubbles00482]

Well, the motor is out, on the stand and I have pictures....



But..........


I'm to high

[dave_rulez]

Nice work you've done man hope everything goes well finishing up sounds like you know what your doing get those pictures up! LOL

[MrBubbles00482]

Sorry about no pics last night, it was a long day and I smashed my right hand pretty hard on the motor. Everytime we would lift up with the picker the driver side mount would get hung, so I pryed up with a 2' long flat blade and WHAM...my knuckles went straight into the motor mount...lol.

Anyway, all valves are good from me looking at them, just carbon build up. Just gonna do new springs and stem seals. Need new cam tower (I guess thats what it is, where the upper head housing that hold the cam bolts to the lower part of the head) gaskets as they are leakering.

On the block, my oil pan is leaking hardcore, wasn't even a gasket, just high heat sealer. Cylinder 4 and 5 broke rings, but cylinder wear looks minimal so hopefully I can have new rings installed and have everything re-conditioned.

Didn't get to see what the knocking was, oil pan will come off today. Gotta adjust my engine stand so I can get the transmission braces off.

Oh ya, and the rear differential is leaking somewhere. There is shit all over it.
