I think I'd be very lucky if both the head and the block are fine. If so I just want the all seats replaced with what ever prevents this from happening. Buying a set of heads from an auto store or eBay may be a more affordable path. Can the cylinder compression be checked by turning the crank...

I was thinking of replacing every thing myself with the exception of the seats. I wanted a shop to do that. I don't remember ever having an over heating issue just coolant leaks. Can a shop test heads off the car for leaks warping and any other perimeters?

I have an 02 4x4 limited with 170,000 miles on it. I'd like to swap the 3.7 motor out. Mine had a valve seat **** out. I know I could buy a remanufactured motor for 2000 plus but I'm not interested in spending more than it's worth. I've read about using other year models and swapping the crank...

I searching for a shop but doesn't appear to be to many. If I find another motor I'd like to have the heads done before the swap. 1st shop I got to said to expect to pay between 1000 to 1300. Seams kinda steep. Was this problem only on certain year models?

I'm the original owner and did routine maintenance and repairs when needed. #1 cylinder has no compression and I can see a valve seat is compromised basically missing. Found some of it in the manifold after tearing it down. Any chance the cylinder isn't damaged beyond fubr? If I find another...

Great info here. I've an 02 limited, 4x4, 170k, and the #1 cylinder went dead one day. I can see the valve a seat is gone plus all the debris that's rattling in the manifold when I removed it. I'm the original owner and maintained it well. I'd just replaced valve cover gaskets, tires, another...

I sure appreciate the info. The cam shaft bolts are torque at 90ft lbs so I hope impact gets them off without stress on chains. Chains appear to be ok. Is there anyway to know there fine by measuring the play or length. Ive seen some vids of people using vice grips and a towel to hold camshaft...

Is there a trick to holding the cam still to remove the bolt? Guess i could stabilize the balancer and put the plugs back in. I don't want to put any stress on chain that it's not made for. I want to tear it down to see the chamber. New rebuilt is to much to invest so i may find a used motor to...

Think you nailed it. I removed manifold and valve seat looks blown plus all the metal shrapnel that came out of manifold. Should i even waste the time to go any farther thinking the cylinder is chewed up.

I would've thought the valve next to spark plug would be inlet for fuel and the other on the side of the exhaust manifold would be the exhaust valve. Really hard to tell whats in the spark plug hole, its small. I see that the plug sits at an angle to the valve. The ceramic insulation was...

Thx boss. Sometimes the answer is so simple you just can't see it. Should i set TDC of #1 before removing cam gears and how to check the timing chains for stretching? I don't want to replace parts if i don't need to. Any good vids you got?

With valve cover off what could i look for before getting head off? Ultimately im hoping no cylinder or wall damage or scoring. Its definitely the inlet valve with air test and #2 at TDC and valve cover on. With constant air pressure at 25psi, valve cover off i rotated the crank at the balancer...

Ok any body out there? #2 cylinder no compression. All others seam good 150+psi. Take a look at the blown plug. Hooked compressed air up and feel it at manifold butterfly. Im looking for references for parts thinking timing chain went and needs changed. Pulling head off to look at valves and...

Just got diagnosis and low vacuum. Guessing bent valve. Would compression test show what cylinder

180k 1 owner limited liberty Running fine and next day turns over but wouldn't crank. No codes via torque pro. My daughter calls to say it won't crank and i think it became flooded after trying many times. I remember the hose to the pcv having cracks so i change it. Pulled the plugs and were...

Bought Atoto A6 Pro A6Y2721PR and wire harness metra abmw-6502 and antenna harness scosche metra dbl din kit 95-6534b. The power ant wire on metra harness connected to amp power on atoto powers the speakers. Id like to get the rear cd to work and steering wheel controls to work hard wired if...

Yes, small amount of coolant that drips from that v shaped engineered after thought slide that some DA created after probably seeing you can't hold the oil filter upright and pull it from the 4x4 3.7. Looks like very bottom of cover it where coolant builds up. The oil pan edge and bolts is where...

Looks like its at the bottom of the timing chain cover. I've cleaned well all around the front and there seems to be coolant that's leaking out at the bottom on the drivers side, runs back onto where the oil pan is and drips on that plastic slide just below the oil filter. Any good how to's on...

It maybe just the lower hose as i found a drip that hit tranny lines and runs back some. Wipping bottom off well to see if the white residue reappears
