Oh no, what happened to the engine and are you putting in a 2hnd motor or rebuilding it?
Ag, basically it turns out that the guy who previously worked on the engine patched it enough for it to run for a while, because there was absolute carnage inside it when it was stripped. There was also evidence of it being worked on quite recently before I took ownership as per my mecchie, and also evidence of the car being overheated many times prior to me taking ownership of it. Surprisingly it ran well up until...it didn't.
It went in for valve stem seals and carbon cleaning, but that snowballed. Here's what was replaced/repaired with a little story of how it happened.
The
valve stem seals were replaced as the old ones were hard and leaking oil. Then it was found that the
valve guides were ovalled due to the
head which had metal contamination inside which chewed up the journals as well as the
camshafts, which were badly gouged and worn from metallic debris stemming from the
oil pump, which seized up due to a locked up balancing assembly, which also ripped the
crankshaft sprocket off and broke the teeth and seized the chain. The oil consumption also caused detonation so the
pistons, rings, gudgeon pins, bearings and conrods were also replaced, but then they found that the
bore was oval so it had to be machined and rehoned. The
oil filter housing is also busted and was leaking, so that was replaced, as well as a
heater hose running from the back of the car that was held on with Pratley epoxy. They also polished the
crank but it was still in good enough condition, and it was basically the only part in the entire engine that was still in workable condition.
I did consider dropping in another engine, but either way, I would have been out the same amount of cash, but going the repair route I know that the engine's weak points are addressed (seizing balancing shaft, incorrect spec oil control rings, hollow camshafts) and I have a 5-year warranty on the workmanship vs 90 days for an import engine.
To satisfy my own curiosity I called Audi and asked them for a price on a head for the car, which came to just over R89k + exchange. Needless to say I did not pursue that route at all.
@Craig_ it's an older Audi A4 with the 2.0T motor. I think the consumption should come down once all the repairs are done, since burning all that oil could not have been good for the fuel economy.
