So a total drama this afternoon that me doubting my knowledge and ability!!
As you may have seen in my post ‘another A2 on the road to recovery’ I have been doing a lot of work on the recent purchased black A2.
New suspension etc etc, and I decided to send my Ecu off to be ‘looked at’
Whilst it’s out of action I replaced the timing belt and left the oil to drain for 2 days as it was black!
The Ecu turned up in the post this afternoon, so I stuck 4 litres of oil in it to flush it through, plug in the ECU and start it up, it runs beautifully and I go to the front to check for leaks etc then a hell of a clattering, sounded like the timing belt had slipped..proper valves hitting piston noise, than ran rough, misfired and stalled!!
Complete panic, rip the covers off expecting to see the belt slack, but it’s fine. Try starting it and it made that awful no compression noise, spinning over with a regular hiccup,
I Hook up compression tester through the glow plugs….cylinders 1 and 2 nothing, cylinder 3…..400 psi!
I’m now assuming I’ve really f%%ed it up, and Recheck timing, put nylon tube down cylinder 1 and turn crank to TDC, check cam and insert pin, all ok, and my extra tippex marks line up too??
Decide it’s broken anyway so try to start it, and it’s slow to turn over, connect the jump pack and it spins fast, splutters into life on 1 cylinder and sounds awful then the rattle stopped and it ran absolutely fine.
I think all the oil drained from the lifters, preventing the valves opening, and the delay in oil get to them was slower than the cam beating the oil out of them? It gave me a big scare and put my on a proper downer, but it was just a big drama!!
