Owner reviews for cylinder head

They replaced my engine head under the warranty no issues

My 21' had coolant in the cylinders and was burning oil pretty good up until 40k when they replaced the head gaskets....then it still was burning coolant and oil and they replaced the head two weeks later. Mines at 75k now and no further issues(knock on wood)

The new cylinder head fixed the smoking, I haven't had any issues since.

My 1996 Super Custom has over 400k on the clock, had to do the head last year thanks to worn out injectors and a dead fan clutch.

as far as i have seen (quite a few but not hundreds) brazil heads are moderately cast with casting defects on the ports and in the valve train oil area german heads look to be cleaner and definately have the date stamps on them

The 2.8L 24v head has a bare port flow about what a well ported 12v one does. However, at low and moderate lifts, the 24v will kill it, which is what really matters.

with the merc don't settle for low spec and make sure cylinder head extended warranty is active

I've had my cylinder head replaced in June. About 3500 miles later, I see smoke coming from the exhaust again!

Dealer just called and said my head is cracked and will be replaced under warranty.

Cylinder head ended up cracked and needing replaced for $4500.
