Oring ?I'm getting an intermittent coolant leak. Very small. But when I do a pressure test of the system it checks ok.
It just happens on cold start ups.
Any ideas?
I'm thinking turbo coolant line based on I see no hoses leaking by the water pump or radiator.Oring ?
Can leak when cold and expand and seal when hot.
You will have to visually track this one down....or wait till it completely fails, then you will find it quick
Take off the cover under the car and do cold start (if it continues to leak), to get an idea of where its coming from.I'm thinking turbo coolant line based on I see no hoses leaking by the water pump or radiator.
I put some leak stop in to hold it over till I can work on finding it. Unless it holds.... which in that case I'll leave it alone.
I never put my cover back on. Leak is mid back towards firewallTake off the cover under the car and do cold start (if it continues to leak), to get an idea of where its coming from.
Ahhhhh....okI never put my cover back on. Leak is mid back towards firewall
This motor has never been apart. Leak is gone for now. I'll tackle it once I get the e46 back together. Hopefully not head bolts.lifted the dead ?, it leaks when cold and seals when hot, looks like turbo rear turbo is leaking but its actually the two rear smaller head bolts.
The puddle usually forms where you described.
The most was maybe 19psi at short intervals. Most the time it's 15.How much peak boost where you running like not rpm related peak but what was the highest anywhere ?
I think it's a turbo coolant line. I'll find it. Thought there might be others who experienced similar symptoms.Its not the head then
He's getting good at pulling heads ...Yeah it looks like coolant line sometimes but it's the head seen it multiple times, really hope it's not
