4.2L engine problems
I was just informed by Ford that I must replace my engine. 97 F150 4.2L w/84K+ miles. Started having oil pressure probs over a year ago. Today, w/pressure guage in place, hit 35 psi at start up, then dropped to 0 as it warmed. Any ideas on not so expensive replacements? Ford wants $4800 + tax. I know other people with the same engine have had to replace their engines to. Does anyone have a different solution to this problem that would be more cost effective?

I believe that replacement would be cheaper than rebuild. There have been some links on this forum concerning used and rebuilt engines. I personally priced a rebuilt 4.2 w/a 100k warranty for $2100. Surely it would not cost another $2000+ to have it removed and replaced. Try to negotiate a flat cost for R&R.Welcome to FTE, I wish it were under better circumstances.

Welcome to FTE !!
I think Thomas is probably right, although (thank goodness!) I have never had to price a rebuild or replacement.
I have no first hand experience with Jasper and other engine remfgrs. But it wouldn't hurt to check.
Maybe you could get a short block and transfer the rest from your motor?
I think you can order a crate motor from FoMoCo. See about doing that and working out a flat rate to do a turn-key job, either thru local Ford or an independant you know and trust.
Best of luck and stick around!

Yes Jimmy, your 4.2L is 2002 and use 5W20, but I think `97 like smathis as my `98 should use 5W30 and for all Ford vehicles the Owners Manual (OM) said "use only and always". If lower viscosity is used the engine will suffer by friction, otherwise if higher is used then the oil will do to engine ducts as cholesterol do to veins, after 3 years your engine will not be lubricating good enough and will runs hotter. My `98 have 95K miles running with the same temp as the first day. It is more important to use the right oil viscosity than the frequency you change it. If this is your situation, I would try this first before spend more $$, check your OM to know the right oil for your engine (or read the oil cap), maybe is not too late. I hope this help.

Thanks everyone for the input and great advice on remans or FoMoCo, etc. Since I purchased the truck in OCT 99 (with 30,800 miles then) each oil change was 10W30. Maybe that helped the engine's demise. 8 mos ago when the oil pressure drop started, and it was diagnosed as "possible internal engine damage" I began putting in 20W50 and that held the pressure up through cold months, but now it's getting warmer, even the heavier oil with STP added doesn't hold pressure at low rpms. Have had 2 independent mechs (one local shop and a Ford Dealer shop) both say same thing - recommend repair by replacement. Will continue my research. tks agn.

FWIW,
I have run nothing but 10W30 (Shell and Chevron oil - not synthetic) since I bought my truck brand new in Feb 2000.
It is a 2000 model with 124,500 miles on it.
I have done a half dozen used oil analysis - all have been very good. 10W30 is fine for our 4.2 and will cause no harm.
That my $.02.
