This is not my first swap, I'm running an ARL with lots of mods in my MK3 Jetta...

I was buying a P150 engine from RyanP in May. It was looking fine, no rust, had 78k miles.

We were installing in in July. It's running with a GTB2260VK, custom tune (Named Tintin) and few other goodies.

When it's waming, it's clicking in compression and the injector #1 balance is off (-2,8) at this moment.

I measured the tandem pump pressure and it's OK.

Yesterday, after many weeks stopped, I had to move the car. I was quite unable to start it at -5*C, I had to use a little shot of quick start. I was starting my MK3 ARL @ -15*C last week WITHOUT GLOW PLUGS, no trouble!!

I was sure I had an injector problem, but now I'm not sure about the head. The cam is OK, no signs of wear.

Any idea?
