head gasket

Also what am I in store for? A top end rebuild? Thanks all

Just to be clear, I am not looking for information on the 15B-F, 15B-FT, 15B-FTE or 14B-T. These engines were all sold to public with plenty of information out there. I am after information on the 15B-T, which was an early (ca. 1995), 8 valve 15B that externally is a 14B-T but has apparently...

I have been lurking the forums for a while, we bought the LC about 1.5yrs ago with 170K on the clock. Fell in love with it more than I ever thought, same will all members of the family, the quiet and comfortable ride is hard to beat. Vehicle is basically bone stock, just high miles. Vehicle has...

Started with a cyl 6 misfire. Then started smoking when cold but stopping after gets to operating temp. Got a borescope in and found this first is cylinder 4, then 5, then 6. Looks to be coolant sitting in 6 😅

Hey guys, Quick question about head gaskets specifically for 1hdt. Is it possible for a gasket to weep oil/coolant or both without affecting the fire ring or having any other issues? I’ve been getting a bit of oil residue and now dried coolant right at the back at number 6 but no issues with...

Hey all! I’ve confirmed and reconfirmed that the HG is blown on my LC. The beast was hauling 2k pounds up a desert mountain at 80mph, blew the top of the stock radiator, and is now pressurizing the cooling system with combustion. Before realizing it was HG, I dumped a few bucks in with the...

The story - I picked up a 1st gen Sequoia Limited with 220k for cheap. Diagnosis from the mechanic who looked at it said it was likely a head gasket. Oil was milky. I've always wanted to do a project like this so I pulled the trigger and started the engine tear-down. I've got the FSM for my year...

Hello, I am selling my 1997 1FZ-FE engine with its transmission. The engine and tranny have 267K mile sand the head gasket was done at 239k. I am selling the engine because I have swapped in a diesel. The 1FZ-FE engine was fully repaired along with some nice add ons such as honed throttle body...

legends, i've been slowly working though my 80 and had to go visit family this summer in new england. long story short is i am going to be doing some work up here before heading back to texas and was wondering if anyone wouldn't mind helping out or eyeballing things as they progress. long story...

1993 FZJ80. I did a full head job 5 yrs/47k miles ago, following the FSM exactly. I used OEM gaskets. Hunting for a coolant loss in my truck (using UV dye) i discovered a small amount of dye in my oil. Praying that it was from my oil cooler i did a pressure test and got 160-170 (dry) across 5...

Hey fellas. I have a 1996 LX450 and I noticed a had to add a tiny bit of coolant over the past 1000 miles. I couldn't find any leaking hoses, and as far as I can tell it has been running fine. I performed a leak down test on each cylinder followed by a compression test. I did the leak down...

Looking for a place in the SF Bay Area for a 2008 LX570 head gasket seal. Looks like a head gasket seal is damaged, white fume from exhaust, coolant getting in. From what I understand this is a 4-6k job and it's mostly the labor that incurs the coat. I've called numerous shops but all of them...

My father repairs tractors and says he always uses it, but ive never seen anyone else do this. Permatex® Copper Spray-A-Gasket® High-Temp Sealant, 12 OZ – Permatex - https://www.permatex.com/products/gasketing/gasket-sealants/permatex-copper-spray-a-gasket-high-temp-sealant-12-oz/ I think its...

Yesterday after a short spin, my truck started to overheat. It went from normal temps to 280+ according to the Scangauge. I was able to get it home, I'm sure I should have just stopped driving when it happened, but I was close and there were other things going on at the time, which led me to...

I recently did a head gasket job on my 2007 FJC. Does anyone know what my timing advance should be at idle? My OBDII reader says its at 20 deg right now and it seems to be running slightly rough right now. It's idling at 950 RPM. I'm having a hard time finding anywhere online that states this...

Hey guys. I'm new here. I have a 2007 FJ with 240k miles on it that needs a new head gasket. Exhaust was leaking into cooling system. I'm in the process of tearing it down to see what's wrong with it. I'm very close to having the heads off the block and I have a few questions about this specific...

As the title says, last year right at the worst time before a move my trusty daily driver LX450 blew #6. The oil is definitely milky and it did run a bit for me to move it on and off the trailer with extensive smoke. All things considered, it made it just shy of 250k miles. I replaced all the...

Just got my cylinder head back from the machine shop today and they told me they cut 0.006 off. According to this post, my head is toast..? The shop recommended me to not mess/replace the valve stems and to not clean the carbon on the valves. I've talked to a Toyota Master Mechanic and he said...

Took the exhaust cam out yesterday and found my 7th cam bearing is very worn compared to the rest. The bolts holding it in we’re not as tight as the rest probably due to it being worn extra. My question is, is this anything to be concerned about?

Hey all. So I rebuilt my '73 1F a couple years ago. I just blew my second head gasket since. (1st was due to water pump belt, resulting in overheating) To be honest I'm not 100% sure what happened this time. Water pump spins but it blew all my coolant out and now my oil is milky. I'm hoping just...
