Castrol 20-50, 100,000 miles or so on a Toyota 20R engine

Once warmed up nice it loses oil pressure at idle at the stop light (electric gauge), blip the throttle it comes right back. Good pressure at speed.
Not all the time, but it seems maybe increasing. Does my worn out engine need heavier oil? I leave a little fragrant cloud every time I take off the past 6 months, only really noticeable in headlights of the poor sucker behind me. Am I doooomed? Pickup is clear, it has oil.

Barely made it home just now, it ran quite hot although steady temp just hotter by 30 degrees once the electric fan finally cut on and at times I left a very nice white smoke trail just like an old plane at an airshow upon deceleration. Hopefully it's a radiator hose or something easy, but it did not smell like coolant and no steam from the bonnet. Oh I hope it's not bad. hmm it misfired a tiny bit. I am not going to look for a while. Nope. Won't do it. (head gasket?)

Sounds like a little inside oil leak as well as perhaps some coolant.

I know 22R's quite well, if it were a 22R I would say the timing chain has worn through the front cover into the water pump.

But in your case it is very likely a head gasket.

100k is low milage for that engine, I would check the oil pressure with an independent mechanical gauge. The oil pump is right on the front of the engine behind the front pully.

That is a VERY old engine to have such low mileage, what is it's history?

Check your coolant level often, you do not want to warp the cyl head.

20w-50 or 15w-40 is fine, don't go heavier, I doubt it would help anyway.
