Well I was bringing some heads to a guy today and I noticed smoke behind my car on the highway. I think it is leaking from the rear main. It looks like oil is leaking between the engine and tranny. A lot of oil leaking. At first I thought it was coming from the exhaust but I dont think it is.
Do I have to rebuild the engine now? The thing just hit 100k miles. I guess a 355 buildup would be good for her. Does anyone know any good shops in IL? I want to find somewhere cheap but good.

if it's just leaking oil at the rear main, just replace the seal, cheap part, its all labor, unluess you can do it yourself.

 

Is it hard to replace? I thought maybe it was hard that was why I figured just rebuild the engine. If it is easy I will just replace the seal. I guess I will call Speed Inc. tomorrow.

Pull the dust cover on the Torque converter, its a place were oil would collect if it leaked. There will be some oil in there, just check for high amounts.

 

I'm gonna pull that cover off tomorrow. I just went out there and looked under it again. Man that is a lot of oil. The whole bottom of the car is covered. It even is all over the back of my car. It was perfect this morning. Then when I was driving it just started smoking like a French prostitute.

 

i put some of that quaker state high milage stuff in mine for about 500 miles then switched back to the normal oil. Fixed it for me. your seal may be more messed up though, I dunno. I have 175K miles btw

 

Check the back of the intake seal.

 

I did change my oil recently. I used Mobil run clean or something like that.
And I will check the seal on the back of the intake. I forgot the LT1's have that problem.
POS just rolled over to 100k. I thought it was gonna crap out at the toll booth. I guess if you put a lot of power out you are asking for problems not to mention the high mileage.
