Again, I am grateful for the support. This is a great community.
When I bought this last Saturday, it had no codes. The oil level was slightly low but within limits, the owner said he hadn't changed the oil since he bought it in November of 2014 so changing it was a priority to me. I brought my obdII code reader with me and scanned for codes and nothing was there. I drove it home to Modesto, CA from the East Bay. I felt pretty good on Monday so I went and bought some conventional Rotella 15/40 and new oil filter. I changed the oil and filter (while in a neck brace -- which sucked), started up the vehicle and got the service engine light. I plugged in the reader and came up with P0307 - Misfire @ #7 and the P1319. The vehicle had 1/2 tank of fuel at the time. I cleared the codes and drove it down the road, parked it, shut it off and started it back up and the service engine light reappeared, with the same codes -- Please keep in mind that I had a neck brace on while changing the oil and had neck surgery 4 weeks earlier...I was exhausted physically and mentally. I re-started it, opened the hood (bonnet!) and listed. I could hear a tapping noise but wasn't really alarmed by it. When I first started it up there was white smoke from the exhaust but I assumed that the vehicle was just cold. The coolant level had not appeared to change from the drive from the East Bay to Modesto.
I am picking up the vehicle tonight from the shop and paying my $105 (they said they could/should charge me $210 because of the time) diagnostic fee. I will be parking it and there it will sit for a bit. Last night I ordered a set of magnecor "leads" so I will be putting those on next week. I put a call in to Dan and left him a message. I should probably email him to check his status. Here's where I stand -- I bought this for $2500. I am willing to invest into the top half of the motor - Head Gaskets and getting heads machined..etc ($1500??). but I simply cannot justify to my current fiance or myself --who I just bought a "fixer-upper" house with - the cost of complete new motor ($5000+).
Reach out to Jeremy Pound, club member, and in Modesto. Maybe he can help out by looking at it and / or know of a better shop!
