3.7L EKG Powertec, engine. SOHC with roller followers,
did you check compression, or just P030x codes???????
and what if its just a stuck valve or collapsed lifter
why not ask for help in diagnosis?
compression bad? on one or more? cylinders, post #
pull the Valve covers, see if there are broken valve springs
or bad cam lobes, or lifter bad? (motion)
if it didnt burn oil , try rebuilt heads.?
ran for 12 years, so what is the mileage>? 300k?
Oil changes, at 5000 ?
the 3.7 may fit...says wiki.
warning, some engine blocks may NOT be same. (filter mounts, engine mounts) check first.
but you can find this at any engine builders web site.
ive swapped many and engine, even wrong engines.?grin
there are always choices, i always have and had spare cars.
so down time is never an issue for me.
but others yes. (rent a car is one option while fixing another)
1: if the block is bad get a short block.
2: if the heads are bad get yours rebuilt , or exchanged.
3: if you blew the engine to total destruction, pistons hit valves? (rare)
then get a used engine, or buy a rebuilt.
or pull yours and take it to any top machine shop and drop it off.
bingo, fixed and cheap too. no middle man, to rip you.
The 3.7 liter PowerTech V-6 engine is, essentially, the 4.7 V-8
with two fewer cylinders.
then later, morphed to the Pentastar V6.
cast iron block, (lasts long time, easy to bore and rebuild)
no rubberband cam belts, real chain, drive.
2 valves per cyl. making head rebuilds fast and cheaper.
forged pistons, not cheap cast.
MOPAR is not POS.
ask engineer Brian Crothers
I run the 3.8L in my 08 JK.
its a real low tech, push rod motor. (ended in 2011)
id fix mine, if it failed
my guess is it is head failure, , so get the newer
rebuilds with pinned, valve guides and run it.
