Well, i have had a head gasket leak for some time and been limping along by dumping in a bottle of the Head Gasket fix by Barr's. Two weeks ago, things went into catastrophic mode on a 100deg day driving home. The top radiator hose over pressurized, popped off and the engine shut down due to all kinds of pinging.
I had it towed home then stuck the inspection camera inside 1,3,5,7 and saw water puddles in 5, 7. #1 looked like steam cleaned. Only #3 was black and dirty. When I get home today, I'll inspect the passenger side of the block and see what it looks like inside the cylinders. I'll remove all spark plugs and crank the engine so that the standing water comes out of the cylinders. I'll also use compressed air to push out the water if needed. I need to figure out how to transfer the pics from my boroscope to my phone, but the pics don't look pretty :-(
I know I can do the head gasket job while the engine is in the vehicle, but I need to address the oil pan leaking issue so i might as well pull it and enjoy the process. The oil pan reseal project involves lifting the engine by few winches then laying under it for the actual work. I hate laying under my rigs to do anything!
If the heads are toast/cracked, I'll pivot as necessary. She has 450xxx miles so my expectations are low. It'll be what it'll be, as they say. I did the timing belt earlier this year, but everything else is still original. I have a great local engine rebuild shop who did awesome work.
I'm going to use this thread as a way to keep track of items, and ideas. I bought my daughter's 3.4 HG kit from this place so I'll get the same thing for the 4.7. Here's their genuine kit for $528 Head Set- Toyota Land Cruiser & Tundra V8 4.7L 2UZ Genuine Head Gasket Set (1998-2006) 04112-50400
they have a cheaper option, brand name is Stone Head Set- Toyota Land Cruiser & Tundra V8 4.7L 2UZ Head Gasket Set (1998-2006) JHS-10451-US for $323.
Thankfully i can reuse the timing kit. I'll need to create a list of the usual hoses, knock sensor harness, and whatever else that are needed.
Engine has DT shortys already so that's GTG.
I'm not sure what else is needed but lmk if you have ideas. The tranny and tcase are bone dry, but i'll replace the tranny input shaft seal. Engine always ran strong with a little bit of startup smoke due to the valve stem seals being worn.
I'll do a compression test before removing the heads get removed and see how the #s look.
Thanks.
