Below is my engine info...have driven the car very little over the past 6 years...total of 700 miles. Had not changed oil during that time...an oversight. The car resides in a heated and cooled concrete floored pole barn...temp extremes are 40F to 74F.
So I take it for an infrequent drive 3 weeks ago. 3 mile gentle drive to the interstate on-ramp...hot rod down the on-ramp...and the remainder of the 20 mile interstate and in town drive was very gentle. Coming home on Interstate I decide to hot rod from 60-80 or so. Floored it and it did not downshift ??? and didn't feel like I had much power...might be wrong since no downshift involved. Coasted back to 60 and did it again...with same result. 3 miles later as I exited via the off-ramp I noticed a lot more engine related noise. Drove the final 3 miles home very gently. Got home, and due to my wife breaking her hand while I was out, I didn't work much on the car.
Noticed milky substance on the oil fill tube and on the visible surfaces under the valve cover...that's when I realised it had been 6 years since oil change!! Drained the oil and it was "milky"...but not too bad. Removed plugs and they were sooty but otherwise OK. Compression test revealed low of 188 and high of 202psi. I put in new plugs, new oil with a quart of Marvel Mystery Oil, and filter.
Restarted and there is a lot of lifter, or overhead noise...pretty loud. Not positive where it's coming from...have Caspers "red light" cam sensor cap and thought I'd read they were a source of noise...wasn't noisy before though.
So looking for ideas regarding the cause...it seemed to happen during the 2 WOT blups on the way home. Suddenly.
Thanks, Bob
