Owner reviews for cylinder head

I have a BMW cylinder head with bent valves waiting for the next white elephant exchange I go to.

3rd is Dorman aluminum. Cylinder head around 128kish. Valve cover gasket and most recent was dreaded tick on the passenger side. Fixed that and good as new.

Daily driver that's had a cylinder head replacement (warranty), on its 3rd oil filter housing(aluminum now, 1st 2 warranty, thermostat, rear bearings went toast at around 150k and had the tick on 1 side.

I recently purchased a 2022 Tacoma and when I left for work the next morning the dreaded P11EC code came on. Lucky for me the truck had 59,450 miles so it was still inside its powertrain warranty and it’s being repaired by Toyota right now. I’ve had the loaner longer than I’ve had possession of my “new” truck.

The cylinder head failure for the 4cyl m264 engine has been given a warranty extension by MB Canada ONLY! Faulty design ruins the exhaust valves.

2023 Tiguan @ ~52,000 miles. I took mine to the dealer after getting low oil lights. I had no oil puddles, so I knew it was burning it somehow. They took a camera and did their tests and told me they are replacing the cylinder head.

Those "cracks" are not due to running out of oil. In fact those are not "cracks" that damage is due to poor casting work at the foundry that molded the cylinder head.

I had the same issue with my 21 TRD sport at 19k miles. They ended up finding “excessive scaring” in multiple cylinder heads. I ended up getting a new short block under warranty. The whole ordeal took a month and the ticket was $18k. I traded the truck in 2 days after I got it back.

Just had my 2020 Limited Tacoma threw an error code, after 6 hours of diagnostics it was a bad manufactured cylinder head. Lucky for me, I'm 4 months past the warranty (only 48k miles though instead of the 60k on the PT warranty), so now Toyota WILL NOT help at all.

ended up going 350,000 miles before one of the heads blew
