Ford blown spark plug repair – Time Sert review Vehicle: 02 Ford Explorer V8 4.6L Many Ford engines from 1997 to 2008 with Triton heads may blow out a spark plug. Many companies have come out with a relatively inexpensive fix that allows the Head to remain on the engine, thus saving a lot of money in repairs. Although I have rebuilt engines in the past, I have never repaired this kind of damage to an engine. I wanted to record whether Time Sert’s claims were as easy as they proclaimed. The answer for me was mostly Yes. The only criticism was that I had no objective idea how much counterboring I needed to do. With the engine that I had, a Lot of counterboring needed to be done and I thought I had gone too far at one point simply due to the amount of time spent with this operation. I have done a second repair and decided to only use a hand ratchet on the counterbore. It took two hours to counterbore alone. I recommend an air ratchet for this reason. Bottom line is that this works; It’s relatively inexpensive; and I was overall happy with the product. As well, I can now replace more threads without buying anything more since it came with 5 inserts.
This complete, extremely high quality kit makes it possible to permanently repair previously non-repairable cylinder heads without removing them from the engine! BIG-SERT kits are an oversize thread repair system that will repair threads that were repaired by standard Time-Serts, Helicoil, Perma-Coil, any other similar coil style insert.
