Since the previous owner’s repair history is unknown, I decided to replace the timing belt.
Before that, I measured the compression.
This was on cylinder number 1.
It’s cylinder number 2.
It’s cylinder number 3.
It’s cylinder number 4.
The mileage displayed on the meter is 165,370km.
I checked the condition of the plugs.
The one on the right is cylinder 1 and the one on the left is cylinder 4.
I replaced the timing belt.
I’ve done this job many times on the TT2, so I’m used to it.
There didn’t seem to be any water leaks from the water pump.
There didn’t appear to be any oil seeping from the oil seals on the crankshaft or camshaft.
These are the old and new timing belts.
The one on top is the old one that was attached, and the one on the bottom is the new one that was replaced.
When I say new, I don’t mean a brand new one; it’s a reused belt that was attached to an engine that was blown up in a TT2 and had been used for about 1000km.
The coolant was low, so I refilled it and tried bleeding it.
When I opened the air bleed pipe on the engine side, bubbles came out.
Could the gasket have come loose and gas is escaping?
It’s possible that’s why the coolant level has decreased…
I thought about removing the head, but one of the exhaust pipe cover mounting screws had rusted and was thin enough to turn it, so I decided to try again at a later date.
