is the gasket type just a gasket with the oring seal on the bottom of it? So it could go on any sump?

Heres a picture i have which shows what i had to do to make the VN-VR sump work on the ecotec, and its got the ecotec gasket above it ....

the rubber is on both sides on the inside, so should seal the whole way round unless the block bolts are through holes.

it didn't have the rear holes drilled either, but they were in the block and as i used a steel VN-VR sump i added them in the right location to make sure it sealed properly!

I hate those cork gaskets. The OEM is not even cork lol.

should work on all ecotec without O ring groove machined in the sump

i've never had an issue with a cork gasket if installed properly ?

VS and early VT use the o-ring. Later models use a gasket

that doesn't make sense, the motor i put into my torana was from a VS and it had the metal gasket with rubber seal, and i believe it can't have been a VT motor cause it had no EGR on it ??

unless its had a pan replaced at some stage in its life.

Could have been replaced before.

The sump gasket was revised in 1999 so a lot of the series 3 got them and series 2 vt onwards.

I was talking to a tech at Holden yesterday and we were talking after market sump gaskets when he did mention that Holden recalled vs to early vt due to leaky sump o rings. They retro fitted the revised type.

Yep spot on vlad thats correct.

A little while ago, we were talking about cracking heads in ecotecs. Well I was getting a ford 4L reco again (no surprise there lol) and I saw a set of ecotec heads in the corner.

I went ahead and asked about these cracking issues.

Sure enough those heads were cracked. But the guy tells me that some crack between the valve seats but only ever a fraction deep into the surface. He just tests them and put them back into service with not one head giving any trouble despite cracks existing. This one had sunk exhaust seats so that suggests it ran hot, it was also on gas.

What got me thinking is the sharp ridge between the seats might get hot enough to initiate the crack, running hot all the time progresses the crack from what I am thinking.

I wonder if radiusing the ridge would help the issue? running cooler and a descent tune would help heaps I would imagine.
