Comp is good, especially for the mileage.
I'm sure the new head or block was machined when it was installed about 100k ago...therefore explaining the high compression. I'm guessing everything else remained the same though...(piston, rings, valves seal, etc)
How much oil are you losing/month?
Are you actually seeing it go out the exhaust, or just having to top off every so often.
I haven't actually driven that much since my last oil change 6200km ago on Apr08. The initial 5 months out of 10 was just sitting, followed by 6200km over the last 5 months period. So far I've added a total of +5L oil last 2 months to keep my oil level between empty-middle. So 10L total including oil change for 6400km, is that a lot? <img src="/forums/images/graemlins/scared.gif" alt="" />
I don't see oil dripping out exhaust or blue smoke. But I do see black deposit coated everywhere behind the muffler (no tail pipe) and very noxious smell from running rich? (sulfur i believe?)
Generic Aftermarket Cat is 102500km old, o2 senser is 28700km old.
My oil pan gasket isn't dripping, but it's definetely soaked.
Rear seal is probably the culpit...does a oil covered tranny confirm that problem? How do i check?
The PVC grommet on valve-cover is not particularly sealing...I see oil residue on it.
Leaky injector seals could be the loss of fuel economy, though unless you can smell gas w/the hood up it is likely more from the exhaust leak.
I do a bit of fuel fume in the summer. Actually, I do see a visual soaked cast aluminum just about 3/8" around the gap btwn intake/injector rail(I hope these are the right terminology) for #4.
I would pull the manifold and if the heli-coiled repaired studs don't work, just re-tap using a standard tap and stud, just a little bigger than the oem metric ones.
Is this refering to the head/manifold studs or manifold/downpipe studs?
