yoeddynz Posted October 26, 2011 Share Posted October 26, 2011 Fill sump with banana skins instead of oil- worked in ww2. Well ok..in jeep gearboxes. But would make it smell nice and be a great story to tell AA man 1/2 hour later after car breaks down eh. Or use ep90.... The method of holding valves out with compressed air- I have heard of it but never seen it done. Do you use a fitting that screws in place of the plug? If you went down that route then you would only need to remove cams and keep shims organised correctly- then surely you wouldn't need to re-do clearances if it was all ok beforehand. Plus you only need to do the inlet valves (no seals on exhaust eh?) You could lift engine up ever so slightly higher to have more room to work on heads.

keltik Posted October 26, 2011 Author Share Posted October 26, 2011 Taking the engine out is a piece of cake so thats no worry. Takes half hour with the right tools. The gay bit is taking the timing chain covers off. Over 80 bolts for that alone. Quote Link to comment Share on other sites More sharing options...

Yea you just use the fittings that come with leak down test kits/compression testers, it works well Quote Link to comment Share on other sites More sharing options...

Do you use a fitting that screws in place of the plug? Yes, and you can make an adapter by hollowing out a spark plug and welding an air fitting to it.

yoeddynz Posted October 26, 2011 Share Posted October 26, 2011 Cool. Every day is a school day! And as for 80 bolts.... just don't bother putting them all back. I'm sure 2 on each side will do.... Quote Link to comment Share on other sites More sharing options...
keltik Posted October 26, 2011 Author Share Posted October 26, 2011 Looks expensive. Quote Link to comment Share on other sites More sharing options...
thegreatestben Posted October 26, 2011 Share Posted October 26, 2011 Would rather do that on a bench. Even if it took twice as long I bet it's waaaaay easier. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted October 26, 2011 Share Posted October 26, 2011 When did you last change the oil? Old thrashed oil will burn readily and can cause worn valve stem seal symptoms. However it is most likely (as most people have said) caused by worn valve stem seals and/or worn oil control rings. Swap in better engine and then use current engine for a basis to build up a ripsnorter of a motor - then nix the shithouse Subaru gearbox and throw a W58 behind it.. WIN11!!11!!eleven!1!

keltik Posted October 26, 2011 Author Share Posted October 26, 2011 Oil is about 5,000km old. Have always changed it at 10,000. Gets a factory filter each time so its been looked after. Number 2 with the oily plug read 150psi, number 3 on the opposite bank read 180psi. I know that doesnt really tell much but couldnt be fucked doing all 6. Had a curry to cook. Oh well, at least now i have another oldschool vehicle to drive while i fix it up. Quote Link to comment Share on other sites More sharing options...
fuel Posted October 26, 2011 Share Posted October 26, 2011 150 seems a bit low. Heck even 180 is perhaps a tad on the low side for a 10:1+ compression motor. I gather throttle was held right open and starter held on for a good 4-5 seconds until compression gauge needle stops moving any higher?

keltik Posted October 26, 2011 Author Share Posted October 26, 2011 Correct, test was administered under the watchful eye of a certified Holden spannerer. Static CR is listed as 10.7:1, factory service manual says 185-210 is the expected pressure. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted October 26, 2011 Share Posted October 26, 2011 Compression test doesn't really show fucked oil control rings if the compression rings are in good nick. Quote Link to comment Share on other sites More sharing options...
fuel Posted October 26, 2011 Share Posted October 26, 2011 that's true but it's rare to see just an oil control ring fail and not the compression rings at the same time. Usually a piston ring land cracks, a ring breaks or the piston edge melts/deforms. I would say the oil burning probably is coming from #2 and it's most likely a ring/piston issue.
