I recently purchased an ‘86 gt in WI and it developed a leak in the oil pressure valve midway to chicago and used 3.5L of oil and created a noise in the motor, does this sound like rod knock or a lifter issue? I changed the oil and it was clean no metal in it and I’ve been driving it with this tick for a couple days and it isn’t affecting the performance or idle. Supposed to be driving it back to nyc Tuesday and I’m a bit worried it won’t make it. Please let me know if anyone has a local shop i can stop out to and have it checked out and fixed. Your advice is greatly appreciate thanks for your help guys.
