Hi Guys,
My T5 starting poor and diesel in sump, so mechanic replace injectors and seals.
He applied air pressure to fuel rail after cover and tandem pump was removed and notice
bubbles in oil gallery.
So head is cracked right?
He thinks damage was caused by someone placing screw in wrong hole, while assembling engine.
Does it sound right?
I will appreciate your help.

Thank you
Kalvis

I'm gonna try and break this down

1. Changed injector seals
2. Tandem pump removed
3. Pressurised the fuel inlet to the injectors, via the output line from the tandem pump
4. Bubbles coming from where?
Yes you got it right. Seals changed, tandem pump removed and presure applied to fuel rail. He told me there was bubbles in oil.
