1997 4.2 Dead...new member
90,000 miles. I ran out dropped off some stuff, got a wash parked it. Next day started it up and nothing... Kept trying again and again. The starter was hitting the flywheel but it wouldn't turn.. Then it started... A loud metallic crack and it started with a loud fast clanking from the motor. A thick puff of white smoke came out of the exhaust. My guy said that it spun the bearings..I changed the oil every 3000 to 5000 miles. I need a new engine. This seems to be happening to many 4.2 owners. He said that the oil pump on the 4.2 wears out about 100,000 miles. His brother works at a Ford dealer and said the life on these motors are about 100,000. I'm going to see about the Hydrolock issue. Have you guys purchased any engines from online? Have you heard of Rhino Engines? They have a 3year 100,000 mile warranty. Here's a link:

This was from Jasper on the 4.2 and what they did for some of the issues:
--Because of issues with low end knocks and the possibility of it
causing transmission problems, JASPER updates the main bearings to
a special design aluminum bearing. This reduces the excessive
crankshaft endplay responsible for those issues providing a more
durable engine.
--The wrist pins in the 4.2L Ford engine have a tendency to become
loose; causing noises and cylinder wall damage that leads to low
compression and blow-by. The original piston pins are a press
fit, where JASPER uses full floating pistons where the piston has
clips on the outer edge to hold the wrist pin in, eliminating the
chances of this occurring.
--Due to loose/noisy timing chain issues JASPER is using a slick back
timing chain. This will prevent tensioner wear to increase
durability.
--To decrease leaks, a Viton o-ring is used to seal the oil pump to
the timing cover. This will provide a better seal than other
rubber materials and increase longevity.
--Blown head gaskets, low compression, and/or overheating can be
issues with this engine.
This can stem from not torquing the head bolts correctly. Most head
bolts are just installed and torqued down once. JASPER is
installing 100% new head bolts and they are tightened with a 6-step
procedure. This multiple step torque procedure is more accurate
and consistent.
