I'm guessing it's possible for timing to jump a tooth or two because of that? Link to comment Share on other sites More sharing options...

How's your cam lobes if you use 15/40 semi syn they should look sweet. Edited 28/05/17 07:57 AM by arronm 3 Link to comment Share on other sites More sharing options...

I got some second hand cams from another fg xr6 turbo. Link to comment Share on other sites More sharing options...

No obvious damage.some Signs of coolant in the pistons but could of been due to disturbing it while the head was removed. I'll take the head hypoperformance on the coast on Thursday and have them inspect, test and machine. Link to comment Share on other sites More sharing options...

Not sure which ones they lined up to but glad I got them to do a complete service and not just machining the head surface! Also Got the 12mm arp head studs, new gmb water pump and just going the ford oem head gasket for now! Still looking at timing chain and guides. 3 Link to comment Share on other sites More sharing options...
