I'm willing to give Graham a prize for the I-5 cylinder head lug.... About the blue smoke he mentions...and I really hate to bring this up, but it's the only thing which occurs to me.... It is possible for the oil ring (bottom ring on the piston) to stick, or to lose its tension (relaxing it so it does not scrape oil off on the downward stroke...). Of those two possibilities, the first might be fixable without teardown. WARNING: The following commentary is offered in the full knowledge that it will be immediately and cheerfully be ripped asunder by other list-members... If an oil ring is stuck, you MIGHT fix it by pulling the spark plugs, fill the cylinders with kerosene or other penetrating-type oil, let it sit for a few days...in the hopes of breaking the rings loose. Then spin the engine with the plugs out to remove the kerosene (Hint: don't lean over and peer into the plug hole while doing this - and be ready to wash off the engine afterwards...) then change the oil and filter, fire it up and see what happened. (This is an old mechanic's trick..many light oils or solvents have been used for this trick. Sometimes it works, sometimes not.) If an oil ring is not working, it is sometimes the result of getting the engine REALLY hot. That can take the temper out of rings without causing readily evident damage - but results in oil usage because the ring does not have sufficnent tension on the cylinder wall to do its job. No way around that one but to re-ring. There are certainly other causes which I have not thought of....others will certainly offer them.... If it's not using too much oil and it's a ring problem, you might just drive it and buy the oil..... Or so it seems to me at the moment. ******************************************************* Al Powell Voice: 409/845-2807 107 Reed McDonald Bldg.
