Do I Need To Rebuild?

[SECURITY]

i was at the drags tonight and when i took off i started getting lots of smoke from under my engine bay due to a melted catch tank hose (dont use the ones they give you!).

when i got to the middle of the track it felt like it was running on 5cyl and i had alot of smoke coming from behind the car (oil frying on my manifold).

i opened the bonnet and there was oil everywhere, one of the catch can pipes burst.

my oil pressure is fine, engine temp is fine, knock is still reading low.

so what could it be?

my spark plugs are a bit black..

ive got no smoke coming out of my exhaust, and no oil in my catch can.

thanks guys, i could realllyyyy use some help.

maybe the extra fuel fowled up one of my spark plugs more than the others because i think i got a boost spike.

are there any step-downs in the catch can piping? or is it the same inside diameter all the way through?

[SECURITY]

its all pretty much the same.

maybe a slight step down.

Comp/leakdown test first

try either removing any step-downs in the piping or removing the catch can altogether and see if things return to normal.

A friend with a 33 had similar issues after installing a catch can and it turned out to be the step-down that were causing the problem.

im pretty sure its a piston

well ill be stripping things off this week and hopefully getting it machined after christmas.

all i need is a hoist.

also, does anyone know anywhere in syd where i can get some decently priced forged pistons?

thanks guys.

don't strip it down if you haven't tested it.

You said that oil was burning on the manifold. That's what the catch can is for. storing oil. If your pipe melted, it's just oil coming out of the tank and burning on the manifold.

The fact that the pipe got melted doens't matter. You can run the engine without any hosing connected to the cam covers.

i took my spark plug out of my #6 piston and ive got a nice puddle of oil sitting in there.

im 100% sure its something in the head.
