Have a 2000 Taurus with the 3.0L OHV
that, after doing a job I was hoping to avoid, I discovered has a failing head gasket on the the rear head.
My local machine shop charges $130 to have both heads machined down, cleaned and vacuum tested. The one thing that worries me about using my existing head is that due to the fact this may have lost a good deal of coolant at one point, I may have a hairline crack that I can't see with my own eyes and really opens up once the engine is hot.
Now, for a car that has 165,000 miles on it, I began to think about going the route of re-manufactured heads that should hopefully come with new valves and springs. I can get a head from Advance for about $150 using their discounts, but when both shopping online, and talking with staff in-store they aren't able to match up my castings.
The casting #'s on both of my heads is F6DE-GC
At both Advance and AutoZone, this is the listing I am finding closest match:
Part # 2FW4
Head Cast # F6DA-GC; Right; OHV
; Complete with Valves and Springs; 7mm Stands. Conical Valve Springs
This seems like the right match, given the conical springs, but with a casting of F6DA (which, by the way I can't find to be an actual casting used), I wonder if this is simply a typo. Unfortunately, their supplier was closed over the weekend and the guys in the store were unable to confirm.
Then, over at NAPA, this is what the guy was trying to sell me:
Part Number: MCY FOR3127A IMPORTANT INFO: w/ Casting # E6AE,w/ Casting # F6DE,Conical Valve Springs
What's throwing me off here is the fact it lists both castings, and that given the E6AE is older I would think they wouldn't be compatible.
So, my question is -- and maybe someone else has experienced this -- is the 2FW4 from Advance the right one, or the FOR3127A from NAPA? Or do I gamble with my head, and while I've got them off just do a valve/spring job?
