Started cleaning sludged engine

[Jon Chimpo]

it won't let me upload. it started uplaying! Lots of VC tick. filled it with 5qt 5/30 1qt ATF. it went away after about 10min or so. drained the motor and filter after about 20min. oil was pretty Brown, with some chunkies. refilled with 6qt 5/30 6-10oz sea foam. it got a miss fire code on #6 which was the spark plug that was cracked I tried to reuse for my start up process.
drove it around the block, oil pressure gauge right at 40.

picking up a new set of cheapo plugs later.

we'll see, but I think this may be a 500k motor!

Maybe it's cuz I'm tired, but what do you mean by "VC tick"? Is that 40PSI at idle? Cold or hot idle? Give us some details on how the oil pressure gauge reads (PSI at cold and hot idles, at 1-, 2-, 3- and 4,000 RPM.

lifter tick. it's totally gone now though. it read 40 at idle, jumped to about 50 at 4k, then dropped back down to 40 during normal driving. it was semi hot when running.

just drove it again with new plugs/wires misfire is gone. felt good, sounded good.

Give it a Kreen treatment for good measure.

I was thinking 60 PSI was the center number on the gauge and that 40 was kinda low (but plenty). I just looked up a pic of a NBS gauge cluster. I'd be happy with the 40 and 50 PSI! Good job!

This thread should be held on to by everyone. If I opened my valve covers and found that I would've been at a loss. Now there's a roadmap, provided it lives a long happy life obviously.

so my wI've was driving to work in the tahoe today. I told her all the stuff to keep an eye on. oil drips, oil burning smell, oil pressure gauge, oil lights ect. she calledencouraged in a panic, and told me the oil like came on.. I had her check the dip stick, and it was full. I was like crap. your only 5 miles from the house, drive home. I left work, came home and it was a cel for the knock sensor... haha oh you!
