T4 2L from a Vanagon (T25)
Engine Code: CU
(hydralic tappets)
It was complete including all the tinware and carbs. It turned over by hand but number three was blowing oil past the head.

It was mostly complete but missing the carbs. It turned over by hand and on of the mountings studs was slightly bent.
Engine with Tinware, Fan Housing and Carbs removed. I could already see at this stage that the left bank of cylinders were gunked up with oil and that the holes in the oil cooler were blocked indicating that this engine had overheated in it's previous life.
With the left hand cylinder head removed number three cylinder was found to full of sludgy oil. Not a good sign but the rings, pistons and barrels would be replaced anyway even if they hadn't suffered this badly.
Looking at the head it's plain to see that they had been blowing oil past the barrel to cylinder sealing surface.
The head after a quick scrub, to get it properly clean it will need to be chemically dipped.
Cylinders 1 and 2 were pretty messy...
...as were 3 and 4. Barrels and pistons usually get replaced anyway as a matter of routine on full builds of ACVW engines as the parts are cheap and give peace of mind. These are examples are definitly toast.
Right hand-side head removed.
Case prior to cleaning. The bottom half was caked with oil.
Plenty of cleaning to do.
Part way through cleaning. I did two passes the first to get off the main gunk the second pass was to get at all the nooks and cranies.
Nearly finished...
The case after degreasing by hand. Once the case is split it will be chemically dipped to thoroughly clean the entire case.
Spliting the case, left hand side removed.
Crank, Connecting Rods, Cam and bearing can now be removed from the righthand side of the case.
