Hemi Posted May 1, 2016 Share Posted May 1, 2016 Nah man , if you have water in the oil it goes milky*emulsifies*. Period. Quote Link to comment Share on other sites More sharing options...
NickJ Posted May 1, 2016 Share Posted May 1, 2016 its definitely out of round, and i dont know why that would be, the new gaskets where concentric. I had a similar issue from dirty threads in the block leading to not enough torque 1 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 1, 2016 Author Share Posted May 1, 2016 Fair enough, engine had been ticked over a bit so I must have underestimated how thin oil gets with a bit of warmth. I guess it's possible it did pistons and a head gasket and pressurized everything Quote Link to comment Share on other sites More sharing options...
Hemi Posted May 1, 2016 Share Posted May 1, 2016 I had a similar issue from dirty threads in the block leading to not enough torque People installing head studs without cleaning the thread and flange hurt my feelings. Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted May 1, 2016 Share Posted May 1, 2016 If you want to confirm bad rings without pulling down the engine. Do a wet test. Same procedure as a normal compression test but you put a couple of caps of engine oil into the cylinder before you test. If the rings are buggered this should tell you, all your results will appear normal, ie all around 115psi. May want to consider a cylinder wall crack as well. I literlly just came in here to suggest this Was driving round in a mini thinking about your issue and was like, oh, he should do a wet test, why did I not suggest that sooner lol Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 1, 2016 Author Share Posted May 1, 2016 Have passed on to do a wet test. Will report with results. Cheers for all the help! Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted May 1, 2016 Share Posted May 1, 2016 Was also having another think Another test you can do with your pressure tester, is take cap off, fit tester and put on like 18psi Start vehicle and reset pressure to 18, then give a few blips on the revs. What you should see if everything is good, is that the pressure should raise then drop back down to 18 psi If it keeps building more and more pressure and not dropping back, then your cooling system is pressurizing from combustion somewhere Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 4, 2016 Author Share Posted May 4, 2016 results of the wet comp test are 1 - 110 2 - 90 3 - 90 4 - 110 the test was done is much cooler conditions so i think that would explain the slight drop in one and four. (and the previous readings were after the engine ran a bit) but yes a decent increase on 2 and 3 seems to indicate rings/lands Quote Link to comment Share on other sites More sharing options...
DoBro Jesus Posted May 4, 2016 Share Posted May 4, 2016 Did you do wet test with engine hot or cold? Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 4, 2016 Author Share Posted May 4, 2016 cold Quote Link to comment Share on other sites More sharing options...
DoBro Jesus Posted May 4, 2016 Share Posted May 4, 2016 Probably why your pressures would be up man, wanna do compression Test with engine warm otherwise your readings will be up the shit. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 4, 2016 Author Share Posted May 4, 2016 previous cold dry comp test had provided similar low figures. even lower infact Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 7, 2016 Author Share Posted May 7, 2016 That won't be helping. Looks like we need to source a new block unless that's fixable? I doubt it though. 1 Quote Link to comment Share on other sites More sharing options...
Hemi Posted May 7, 2016 Share Posted May 7, 2016 Shit. Cracked block. That's impressive. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 7, 2016 Author Share Posted May 7, 2016 It seems to have only cracked into water jackets so I'm expecting to find damaged rings too. Has something happened to cause damage this extensive? Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted May 8, 2016 Share Posted May 8, 2016 Not cleaning out thread before winding in head bolt is a possibility. If there is oil slash shit in there you can end up putting alot of force on the threads trying to compresse whats in there Not saying that is what has happened. But it is one possibility Also sorry to hear you're block is fucked. Atleast it answered a few questions Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted May 8, 2016 Share Posted May 8, 2016 A replacement block shouldn't be too dear. They're.getting so.old now that most need rebuilding now anyway. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 8, 2016 Author Share Posted May 8, 2016 Yeah we arnt that upset about rebuilding it, just need to actualy locate a block Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted May 9, 2016 Author Share Posted May 9, 2016 dad spoke with the engine shop that did the headwork, and they rekond that cracking between water jackets and bolt holes is fairly common and that he wouldn't be that worried about it and that the head gasket will seal it. its two water jackets and a bolt hole involved so naturally i think there is another issue somewhere involving the oil side of things and currently the block is out of the car ready to be torn down, but naturally im rather hesitant to agree with the shop saying the crack in the block is okay. thoughts??

NickJ Posted May 9, 2016 Share Posted May 9, 2016 where does that crack end? could it extend down below the water jacket or has it stopped within the water jacket? Quote Link to comment Share on other sites More sharing options...
