Pulled the head gasket. Looks like it was done before.
Looks ok, compared to a lot if other here. I did this as PM at 172k miles.

However I can see some deformations on several cylinders. Any thoughts on the pictures.

Just noticed that it looks like some of the water jacket ports are clogged. Maybe head gasket stop leak?

Fwiw. I have always looked at the two half moon shaped thingies near the front of the engine. Below valve cover??

If the gray factory gasket seal ooze is still there, then it has OG head gasket.

My '96 had leak stop. The coolant had a reflective metallic shimmer to it.

Still had the grey FIPG but noticed paint marks on the back of the cam gears.

How do you differentiate between this Permatex gray silicone and the gray factory silicone? Even when the half moon silicone is not gray, that doesn't always mean the head gasket has been replaced.

Cams look clean, I think the head was pulled awhile back. I bought it with 152k miles. I looked up the records from Lexus and it had regular service to 125k miles. Didn't see anything about HG repair. Looks to have the old style head gasket.

Here's what a blown (original design HG) looks like...mine from 2010 at 202,000 miles.
