Just got news from my mechanic about the engine in my '78 262. It was running fine until I took a long fast cross-country trip. Halfway through the trip Seka started to make ticking sounds under the hood. I took her into her mechanic and got the news that was inevitable. The cams are starting to wear to the point of causing the undesired ticking sounds. The mech said I could drive it as is for awhile as long I didn't take anymore long trips but that to have the heads rebuilt would run around $3000.00. I really want to keep a PRV6 in it and am considering replacing the B27 with a B280F. Has anyone done this? I currently have an M46 in it and would like to keep the manual transmission. When I mentioned putting a B280F in the 262, the mech said he would need a donor car to get all the proper electronics and sensors for the swap. He also said that he thought he would have to use the tranny out of the donor car to do the swap. He also mentioned swapping the B27 for a B21 or B23. I'd like to keep the uniqueness of the V6 in the Bertone. Maybe I should save up and just get the heads redone? Any advice would be appreciated.
