Nope not since I had the head milled...machinist had to take 18 thouoff it to get it flat though. Maybe need to do another one? Would that stop the ether igniting though in the cylinder? With ether in all 4 cylinders or in Inlet manifold she still just constantly cranks but no sound of it being ignited Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted April 27, 2017 Share Posted April 27, 2017 A bent head can be more than just, Oh, the head wont seal on the head gasket " sort of thing. Can effect valve sealing etc So I guess what i should have asked is, did the shop that machined the head also vac test the valves to make sure they are sealing? Because if they arnt, then you will have no compression, 1 Quote Link to comment Share on other sites More sharing options...

NickJ Posted April 28, 2017 Share Posted April 28, 2017 I had a similar fault in an engine, all the cranking washed the bore, dropping compression to the point it then masked the fact I had fixed it 10 moves ago That fault was an ignitor module, even though it sparked, it had no punch +1 for compression test 1 Quote Link to comment Share on other sites More sharing options...
Lunacy Posted April 28, 2017 Author Share Posted April 28, 2017 Compression tester on the way...hopefully clear things up when it gets here next week. In the meantime if anyone has an igniter or ecu I could try out let me know please Guess if compression is way down then that may be the root cause... Better start building up that bare block haha Quote Link to comment Share on other sites More sharing options...

Valves weren't pulled out when he did it. I reinstalled cams buckets and shims, and timed everything up. If you have the chance to check it out that'd be mint, I'm on a ship in the port and car is down near the cement dome. Cheers Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted April 28, 2017 Share Posted April 28, 2017 Just out of curiosity, when you pulled out all the buckets and shims, did you label them so they all went back in the original spot? Quote Link to comment Share on other sites More sharing options...
