    I used Amsoil in my 2000 Chevy 3/4 ton. I worked with a guy who was a part time dealer, and he offered me a free oil change to try plus sponsorship for the derby cars. At 6,000 miles I sent in an oil sample for analysis, and it came back clean. The truck had 189,000 miles on it when traded in, with no engine or transmission work ever needed. Good stuff in my opinion.

    I am still reveling (that's a 25-cent word for happy as a pig in slop) in the new thermostat for Ham's '48. We went out for a show and tell last week on an 88-degree afternoon and the needle eased up to 160 and as we cruised it would slowly ease up to about 175, then come back down to 165 or so as the 'stat did its thing. It DID NOT run up to 211 and then come back down. No stress anymore - either on the engine or the driver!!!

    I'm almost getting complacent about watching the Temp gauge...

    I'm worried about this being a rabbit hole. You guys are usually the careful ones, and I'm usually like heck with it just run her dry.. but this case I'm torn and am doing the right thing. while it seems extreme yanking apart the engine, trust this guy completely so I'm going along with it. I think the oil leaks are finally solved. That would be amazing.. The clutch is fixed at the slave cylinder. Easy fix. and the master cylinder got warranteed again, so brakes work not soft. Anyway it's operational. but in the process find the milky oil. I'm thinking he found something. He is very good. I am worried what it is. A crack? Yuck. I'm certain that I could build his thing better and better. So if this is just hot rodding it a little at a time I'm against it. All I want is good enough.. so...it'll be weeks, not days.

    So I'm saying, yes,I will have a decision to make if its not the gasket.

    And normally I'd chunk some soup in it to hold it tight.

    But what if I blow the engine?

    Anway, first thing is in a week or two is testing the gasket.

    If it is a head gasket Az it must be fixed or eventually, even with stop leak measures, it will stop running. If it is pumping water into the crankcase it will quickly ruin the bearings and potentially destroy a lot more. If it comes back diagnosis head gasket, it is time to at least change the head gasket. Depending on the miles and how much water is in the oil, will dictate whether or not a full rebuild is in order. A crack in the head can be detected at the rebuild of the head when it comes off. A crack in the block can be more difficult with the engine block in the vehicle, depending on where it might be and how small or detectable it is.

    Cracks are usually a result of a freeze up in cold climates, or a severe overheating event. There are many other things of course but yours has been running well for a while. I would not expect a crack.

    Resist that temptation. It is a temporary fix at best and in the long run adding "soup" gunks things up so badly you end up fixing several issues once you have to address them.

    No matter what racing or car legend put their face on a can, don't go with the soup.
