Just changed head gasket as started missing, on number 4.Rebuilt and ran great for 5 minutes.Turned it off to check fluids ,restarted and the bloody thing started missing again

Took out plug and it was wet again. I now suspect it has cracked in an inlet port I hate cars ,thats me now on the hunt for a new head.

and before its pointed out i know i should have had it pressure tested.

any body want a ported ybp as a paper weight

Hi mate, sorry to hear about the problem but i would check the block as well. Had same prob with my three door. put a stage three head at the cost of a grand and it was still the same. think the block liner or something was cracked, but never investigated further as i was still pissed off for spending a grand and still having the problem. so sold it.

Just a thought.

My block had cracked on No3, you could not see it to start with but a little rust stain appeared after leaving it overnight.

Sorry to read about your troubles

Well the heads off, the bloody blocks cracked so thanks to the guys who posted yesturday you were spot on .

So now got the job of trying to track down a new block and got it all machined again, just great

bud-weis

common problem unfortunately

hope you sort it

block is prob cheaper than the head

escossie560

will have to see got to find one yet, then long stud again ,ect what a pain in the arse

the block cracked on my saff when i thought the head gasket had gone tits up,i spotted it when i was cleaning up the surface of the block ,it does seem to be a common thing

wouldn't installing liners be better than replacing the block?

escossie560

maybe open to all ideas what are liners good for, i know they use nikasel(spelling) liners on rearly big powered cars, but what are normal liners like?

Arnie

what kind of power are u running? Installing liners are quite cheap over my way, way cheaper than a new block, I guess it all boils down to cost

escossie560

At present 450 bhp on bd10 plus gas but whilst in bits going to bigger cams so 500 plus and gas. It will need to be solid

JonnyBravo

I know of a few race engines running 500+ hp on normal liners that have been fine, they dont ofcourse do many miles though so it would be hard to judge if it would work well enough in a road car.

Real bad luck that, is the crack visible then ?

escossie560

It is visable now ,but checked the bores before fitting head gasket and did not see shit ,dont suppose we were looking hard enough
