I have to replace the valve cover gasket and will keep this video as a reference. I've been dreading this task for over 2 yrs now, not a major leak but the valve cover edges are pretty wet, will get a drop or two on the floor once a week. Truly Appreciate you taking the time and helping others.

Hi! Great video and clear! Can you tell me how you got the last bolt near the firewall out? Did you use a diffident tool or were you able to get a straight socket in there?

@SMAutoRepairLLC 11 ай бұрын

Hey thank you, a socket and ratchet but it will be almost all by feel

Replaced my gaskets and reinstalled everything to wind up with a no crank. Any tips? All I can think is the pcm connectors aren't seating right.

@SMAutoRepairLLC 10 ай бұрын

That would be the most logical try to reseat the pcm connectors make sure they lock completely.

@fangtastic4tb 10 ай бұрын

That was it, the age on these connectors is showing for getting them to lock down. Thanks for the video @@SMAutoRepairLLC

Do the bolts have to be put back in a certain sequence and or torque? If so what sequence/torque?

@SMAutoRepairLLC 6 ай бұрын

Working from middle of the intake manifold out in a cross (x) pattern 44inchlbs first pass 89inchlbs second pass.

@SMAutoRepairLLC 6 ай бұрын

A nice snug feel with a 1/4 ratchet will get your pretty close. These generally don’t have an issue if the torque sequence isn’t perfect.

Is this something that can be code-less?

@SMAutoRepairLLC Жыл бұрын

Yes For Sure, Actually More Often Then You Would Think A Check Engine Light May Not Set Any Codes For This Condition.Using Live Data On A Scan Tool Is the Easiest Way To Diagnose This You Can Look At Your Fuel Trim Values And Can Also See Previous Misfire Data For Each Cylinder Even With Out A Trouble Code Being Set.

@@SMAutoRepairLLCThanks for replying. I’m just now seeing this. I’m still dealing with an issue that seems exactly like what your customer complaint was. I start it up and it immediately feels rough, idles rough and sounds different. As I drive and the engine warms it seems to drive pretty darn good. Come to a stop light and idles rough. I just changed all the ignition coils to NGK units to rule that out. Looks like I’m ordering a set of intake gaskets. I’m wondering if simply tightening the intake bolts might work? Also, I feel like when this all started for me I started hearing a weird sound from in the cab… almost like a vibration sound. I thought it was coming from in the dash. Now that’s gone but I swear the engine, in cab, sounds like a diesel.

Where the circle gasket goes

@SMAutoRepairLLC 7 ай бұрын

If your set includes the circle gasket, it is for the throttle body. Throttle body to intake manifold.
