Hi all, first post here. I just bought this 88 turbo for $2700 with some mod.Love it.

I drove it 100 miles to get it. On the way home it ran out of coolant and started to get a little hot and I stooped asap. Lucky I was watching the temp guage all the time. I refilled it and it ran fine. Doesn't overheat anymore.

However, now it leaks oil under the engine, just behind the crank pulley. It drops in the middle in the front of the engine. I am not talking a few drops, with the engine running, it's about 1 drops in every 2 seconds. Doesn't drop much after I park it for a night. I read a few other post and I am suspecting it's the main front seal.

So, here is my questions: What is a main front seal? How much to replace it?

main front seal is the seal to the front of the crankshaft pulley i belive correct me if im wrong guys, its also possibly it can me your camshafts seals. there in the front by the cam gears and its possible to leak behind the timing belt covers down to the bottom so it would appear its the main seal, this is what happened to be. luckly i found that the camshaft seal was pinched leaking oil

Welcome to the forums man,

Yep, sounds like the front seal. The seal is about 15$ from Toyota. Replacing it is not the easiest task for a beginner, but nothing special if you got time, and tools. If you're paying a shop to do this, it would probably be about 1.5-2 hours of labor.
Good luck!

I bet everone is going to say just pull it and do it yourself. Its the seal that is around the crank, prevents oil from exiting the block. I dont know of any other way to explain it. Its not cheap if you take it in to have it done though.

Thx guys! anyone have DIY on the front seal?
I love those rims and that's part of the reason I bought this. It's a JSL?? I forgot. I haven't look in the back of the wheel so I don't know how wide it is but I am running 245 on the back.

You have to remove the oil pan, this will give you a hint of what's involved.

I dont know if I read the thread correctly, but For the front main seal all you have to do is remove the radiator, thermostat housing, the top timing cover, the AC compressor, all belts on the Crank Pully, get a 19mm deep socket and a nice wrench w/ some leverage and pop that bolt loose and use wiggle the pulley lose, and use a puller for the timing belt gear, the seal is right there, use care and a flathead and pop it out, while ure that far in replace the tensioner, and the timing belt and the cam seals and other oil seal in there while you're at it... +1 point for me :) because i changed tht one week and had to replace the lower belt pulley the next week. If you're a novice give yourself a full day to do this job correctly, and make sure you set you timing back per the TSRM when you put everything back together.... have fun w/ your Supra.
