What in heavens did you do to be silent since…?

Edit: I’m thinking after posting you’ve gotten a handle on the temps.

This is often true, and low oil pressure will cause a top end leak. Good idea to do the shop vac test, oil pressure test, and note the temperature it starts. I had one with broken oil pump gears that had low oil pressure but the oil pressure would not get low enough to tick until the engine was warm. I was sure it was a slipped liner until I checked the oil pressure.

I'm reading all this but want to also let it be known that these engines aren't ever truly *silent*. There will always be some kind of low key engine noises that can be described as subtle tick tick ticks. Obviously the difference between a problem and normal lies within the amplitude of whatever's being heard.

I will say, once I fixed the slipped kinder it has been silent for several years. Frequent oil changes, etc. As quiet or quieter than my other cars. It is possible.

I have to ask again vs assuming…. How did you fix the slipped liner…? Drop the pan and pin it…??

I had the liners on the driver side pinned. Took it to a guy here, RoverMasterTech or similar, shop in Jersey by the shore. Worth every penny, fixed bunch of other stuff too, one of, if not the most honest experiences I have ever had a mechanic.

There are write ups on it, after seeing it done, it is pretty simple. Drop the pan, run a bolt through each cylinder and put a nut on it. Basically. I would attempt it myself now that I have more experience, only special tool is an angle drill. From the above, it looks like you have enough skill or guts to tackle it. I would take the opportunity to replace the upper oil pan gasket while you are in there.

I would check it is not low oil pressure, I had mine checked before I excluded the pump. If you have done the chain, you probably inspected the oil pump. Or an exhaust leak, which is super easy. I just did mine looking for the source of my misfires. I have a leak at the manifold to exhaust pipe junction, I need to add another gasket, but you cannot hear it, only shows up as bubbles in the soapy water.

If I sprayed water on the block, drivers side, right at the time it started to tick, it would cool down enough to stop the tick. The block contracts around the sleeve. That was my clue. When I took it to the shop, he identified it immediately. Mine got pretty bad, I drove it for a couple of years as it was mostly just annoying as I tried to trouble shoot every possible cause. There were no other symptoms, ran strong, no codes, just the noise tied to engine speed and temp. Some people have fixed it w a low temp thermostat. Have you noticed a correlation to temp?

You mentioned cylinder 5, that is where my head gasket failed, I wonder if the gasket failed after being pounded on all those years? If you wanted, you could probably just pin #5, but I would probably do them all while you are there.

Thanks for the explanation redrover. You had mentioned exactly this to me sometime last year and that mechanic in Connecticut said he doesn’t pin liners anymore. Do you know where the write up on here is….?

I don't recall where I found this, but I've had this in my resource files for several years since I anticipate having to do it at some point. I'll have the engine out this summer so will probably tackle it then.

Thats the same document I have.
The guy I used was in NJ, not CT. If that matters.

It sounds to me like it is top end. I having ordered an oil pressure gauge and I am going to see what kind of pressure I have. Hoping it is just a bad oil pump.
