Great work!!! Love to hear DIY stories!UPDATE!
So I ordered parts from scuderiacarparts.com out of the UK in late February. Despite saying that the parts would be available within 2 weeks, I didn't get the parts for SIX weeks! I've used them in the past, and they were slow to ship last time as well. Luckily, I have 3 other cars to use. Arg, anyway, saved a ton on the parts compared to dealer, even when including the shipping cost from UK.
Total parts and shipping: $395.34
I ordered two solenoids (only one was not working, replaced the working one as PM), 2 solenoid gaskets, 8 spark plug gaskets and 2 valve cover gaskets.
Taking off the cowling, wiper motor/blades, taking out the ignition coils, unhooking various tubes and the fuel injector cables were a pain. Getting to all 14 valve cover bolts (on each side!) was also a pain. Took off the valve covers, replaced the solenoids, inserted the gaskets, used Permatex "The Right Stuff" as additional seal on the valve cover gaskets. Put it all back together and....voila! Car runs like a dream, no annoying rattle at any time (startup, during deceleration, etc.).
It's probably an 8 hour job, start to finish.
For the record, my car is a 2007 QP Automatica wet sump.
Will using Permatex help with the seeping valve cover gaskets? I've never used the stuff, but I am about to perform a similar service on my dry sump car. I have new gaskets but I haven't decided whether or not to use an additional sealant. Anyone with advice on this would help!
