    No oil to the cylinder head

    Howdy everyone, thanks again for all your insights. After exhaustive research I have come to the conclusion that it's time for a new engine. Given the combination of issues it'll be cheaper to replace than repair. For the time being I may heavily coat the rocker arms with a high heat grease, use...

    No oil to the cylinder head

    Dang, I was really hoping after that last post someone would have some brilliant guidance. I think in the next couple weeks I will drop the oil pan to check the pump and look for a possible blockage. Any other suggestions while I'm doing that?

    No oil to the cylinder head

    Really appreciate all the responses! I'm including some pictures. The rocker arms will look somewhat oiled because I oiled them to run the engine so I could observe. I included a pic of the crack also. If I reasonably thought the cracked head was causing the oiling issue, I'd replace it. I'm...

    No oil to the cylinder head

    Howdy all, I've been having some ongoing issues with my TJ. Hoping someone can lead me in the right direction with solving the problems. First I had a loud chirp/squeak coming from the engine. Discovered there was a rocker arm that was dry and rusted. Changed that pair of rocker arms and...

    Loud squeak / chirping noise (not a belt or pulley issue)

    Alrighty, new issue. I replaced the front pair or rocker arms and pushrods. I cranked the engine no squeak or chirp but I'm getting no oil to any of the rocker arms. I make a closer inspection with a flashlight and find some sludge in the cylinder 4 valve with a distinctive green shine to it...

    Loud squeak / chirping noise (not a belt or pulley issue)

    I've gotten mixed reviews about using oil treatments but something I will consider if replacement rocker arms and pushrods works but I have a reoccurring blockage. Have you ever had any issue with an oil treatment breaking up a large build up and causing any additional problems? I haven't...

    Loud squeak / chirping noise (not a belt or pulley issue)

    Alrighty, update! I pulled the valve cover and one of the rocker arms on the front pair is bone dry. Not getting any oil. I couldn't see through the pushrod so I blew it out. The clip/bridge that connects the rocker arms seems to be bent, which is odd. I don't want to put it back together until...

    Loud squeak / chirping noise (not a belt or pulley issue)

    I pulled the serpentine belt off and started the Jeep. The chirp was still there without any of the pulleys turning. I didn't have long enough stick but found out a golden rule fishing ruler works just fine for finding engine sounds. Lol. The sound is definitely coming from under the valve...

    Fingers crossed. Lol. If I can't find the source up top I'll start looking at issues underneath. I'll need a rear main seal soon anyway.

    I gave that a look. My dad suggested maybe a vacuum leak. May need to find a way to test those hoses. By appearance they look fine.

    Mileage is unknown. The odometer reads just over 140,000 but the speedometer is not correct. The previous owner didn't adjust it for the larger wheels. The oil is good and clean on the dipstick. Although, I let the shop that was working on my rear rotor breaks change the oil and I noticed they...

    Loud squeak / chirping noise (not a belt or pulley issue)

    Okay, I've located the area that the sound is coming from. It's definitely coming from around or under the valve cover. Seems to be especially loud near the front (towards the bumper) of the valve cover. Could a squeal/chirp sound be caused by a bad gasket? Or am I likely looking at something...

    Did you have any other indicators that led you to check the thrust bearing? I haven't noticed any issue other than the chirp. Performance seems normal. Is there a way I can check for this issue before buying parts and putting the work in?

    So, I'm looking for a rubber gasket where the harmonic balancer goes into the crankshaft?

    Loud squeak / chirping noise (not a belt or pulley issue)

    Howdy all, I'm having a loud squeak or chirping sound coming from the engine of my 2004 4.0 Wrangler. I've taken the belt off and verified it's not a belt or pulley issue. The chirp begins the moment the engine starts and is synced with the rpms. It makes the sound in idle and while driving...
