What to do? 1 cylinder low

[mccurdy]

So I did a compression test that yielded 2 low cylinders (3 and 4), so i took it to the dealer to have them do a leakdown test and analyze where and what the exact issue is. Upon their compression test and leakdown test, they say its only cylinder 3 that is low.

My readings were for dry: 180 180 150 155

Their readings were 175 175 150 175

Personally I think the dealership is fulla idiots (especially since they test drove it on a potentially blown engine). I did my test at WOT dry AND wet.


Now, I'm curious. If they are right, and its just cylinder 3, that likely means bad valves or a bad piston ring (or cylinder wall). Since it is not in the service level limit yet, what would be the ramifications on continue driving it until I have the means / time / necessity to rebuild the block?

If its the rings or cylinder wall, is the damage already done, or will it get progressively worse? Before i tested the compression, the card pulled pretty strong (tick was noticable however). I thought to do a compression b/c i had oil spraying under load from my dipstick (blowby?).

What you guys think?

what were your wet test results?

200 205 190 195 for wet test.

Any before you say "It's your rings!" , adding oil to the equation is always going to raise your compression whether the rings are 90% blown or just starting to age. Plus im aware my rings appear bad, what im asking is how damaging will it be to drive on it when im still above service level limits???
