Engine is as follows:
B-headed 4.6L 4v
03 cobra block
03 cobra crank
03 rods/bolts
17cc dish je pistons with valve reliefs
Modmax plasma moly rings
Clevite rod/main bearings
Mmr imrc delete
Mmr oil pump
Mmr water pump
Mmr side bolts
Arp head/main studs
Heads decked .030" w/ 5 angle valve job and new stem seals
Stock cams degree'd
Oem 03 Cobra head gaskets
New timing set
Mmr oil pan
Got a noise. Definitely drivers side at the top of the motor near the valve cover on the front of the motor. I'm assuming timing chain tensioner. Doesn't do it unless its been idling for over 10 minutes. Otherwise the motor has no noises other than the typical forged piston sound. Motor is on its first oil change. Motorcraft 5w-20 with Lucas engine break in additive.
Any suggestions? Mechanic that built the motor wants to replace the tensioner and charge me $400 to do it. Is there anything else I can try before it gets to that point? Is that even a fair price? I plan to change the oil today as the car has seen about 500 miles now on break in. Any chance that could fix the issue or am I just wasting oil and money?
Thanks in advance.
