Re: Head gasket issue?

So felpro installed and no issues :-) Whilst in there checked valve lash and it was all over the place and didnt match the clearances given on the cam card so was badly shimmed at stock values. Once reshimmed then moved onto the timing and the inlet cam is 9.5 degrees out should be 12 ATDC and got 2...

Re: Thoughts

Cannot find the cosworth gasket. Gone for felpro, only running 22psi hopefully the ARP studs with this gasket will suffice. If I read correctly others have used timecerts and machined the arp nuts to fit the limted space in the head? TBH others have standard bottom end and got away with around what ...

Yes, finally got some time to at least get it to some sort of reliable motor. I have found previous threads all over the place on here before I owned it.

Seems like I have a HG issue. Water was being pushed into the expansion tanks (non pressurised catch can). Car is on a cometic MLS GH, and ARP studs. Just done a leaddown test and on cylinder 3 it is pushing into the water (radiator level rises slowly). Car has never been right since purchasing it b...

Hi, recently had to take the cams out for headgasket tighten. Anyway during this I noticed the van has JWT adjustable sprockets and BC version 2 cams but was set up on the default slots that appear to have a lot of lash which I would imagine is not ideal. The slots are not worn. No such backlash is ...

Well cams out and the nuts were less than 55lbs with the most "loose" being the ones next to the cylinder that shows slight coolant leak. Have re-torqued to 86lbs and system under test at 1.2 bar and so far no pressure loss in 20hrs. It is on ARP's and cometic HG. Would you guys loosen say 1/4 turn ...

Ka-t powered van mild accel run

Ignore the lift off compressor surge this is going to be history as removed double spring on Greedy BOV.

This was a slow pull away then around 60% throttle

This is a seven seater people carrier around 1680kg
