Lost my A/C on the way home from work. Popped the hood and found a big hole in my timing chain cover along with a broken belt. Don’t know what part number to replace the timing chain cover and timing chain?
Do you
have the same problem?

Hello,

Ouch! I have had similar things like that happen to me before. One time I got home from a friend's house, parked my Chevrolet Cobalt in the driveway, woke up the next morning and was going to run to the grocery store for some breakfast, and the vehicle would not start. Come to find out that somehow over night a timing chain tensioner had given way and when I went to start it, it jumped time. It has an interference engine it, and, to make a long story short, the junkyard gave me $100.00 for it, bent valves and all.
Anyways, I sympathize with you. I have included the information you requested in the diagrams down below. Please, don't hesitate if you have any other vehicle related questions. It's what we do. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed. Thanks, Alex

Doing timing chain replacement including guides and tension-er's. The new left side (driver side) tension-er does not have the small drilled port in center of plunger that is actuated by the HP oil system. Old one removed does have this opening. The new right side tension-er does have this opening. Assumed this was intended for oil flow or return. Checked 5 national auto supply chains and 2 Ford OEM dealers and none of the left side replacement tension-er have this opening in center of the plunger. Question, did Ford do a modification for this part and will the lack of this opening in the center of tension-er plunger effect performance?

Hello,

Ford did do a modification to the tension-er which will not affect the performance, you are good to go.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

When replacing the tensioners for the timing chain, at the mileage of 99,000, should the chain be replaced? Are there any other parts during this work which is being done in conjunction with cam shaft senor replacement that I should address?

Since your going to be messing with the chain, check the wear and replace it if it is 50% of the allowable or if its less of the allowable slack.

If I were you I would just replace it no matter how worn due to the fact that it takes time to measure slack, and while you have it off why not replace the chain.

Just check the wear and replace as needed, you problably wont have to replace it but I would.

I'm hoping you can help me, My original problem was a very loud ticking in my truck I found it to be loose timing chain. I replaced the tensioner and arm and it resolved the loud ticking now I know this sounds stupid but it has a mild tapping sound now- almost as if you can hear through the oil resevoiur the chain hitting the arm i've checked the timing and it seems to be right on. I'm just completly stumped at this point, if you have any ideas as to what could possibly be preventing the chain from tightening, I would be ever so greatful thank you if advance for your help in resolving this for me

STUMPPED!

HI there, did you check the chain for stretch and the condition of the teeth on the crank & cam?

OK,
I will have to go get a manual and have a look at the system I will re post my thoughts a bit later.

Engine Mechanical problem
2004 Ford F150 V8 Four Wheel Drive Automatic

I just did a timing chain, guide rails, and tensioners on my f150 5.4 lariot 2004. The front engine noise was a very distinct rattle at initial start up it is still there until the oil pressure builds then the rattle sound goes away. The tensioners do not seem to be holding oil pressure after the engine is shut off, they seem to be bleeding off, it takes about 20 min. Of sitting. Iis there a check valve or a bleedback valve that is faulty that could be causing the tensioner to bleed off its pressure. The old tensioners were spongy when I removed them, I don't think the new ones are performing any different.

There are revised cam phasers for noise, as well as recommendations to pull the front cam cap and inspect oil feed line

also make sure you are using 5w20 oil and thicker oil can cause noise

I have a 2003 f-150 lariat supercrew with the 4.6l triton. Long story short a lot of water in oil due to warped head. Had head resurfaced and shop took off the cam. The installed the cam back on the head when done. I 0ut the motor back together. Crank but no start symptom. I figured it's 180 out on timing so I tore it back apart and upon removing the timing cover and chain the passenger side cam/phaser turned. I tried to turn it and I get about 20 degrees either way and no more. I'm suspecting a valve is hitting on a piston. Did the same thing with timing chains on and turning crank. Goes so far then sudden halt. Can I take the cam off and reposition it without having to tear the whole damn thing back apart? And if so can someone please give me a step by step on doing so. I cannot afford a shop or mobile mechanic so I'm having to do this the at home in my spare time after. Need to get this thing right and running as it's only vehicle and I have a family that depends o this p.O.S. Running.

The fact that you cranked it out of time concerns me as the valves may be bent. When you get timing back, do a compression test before starting.

I attached a picture of the timing marks for you to review

Will definitely do compression test but I know the valves and piston didn't hit when I tried cranking it as I turned the motor by hand probably 100 times before trying to start just to check that everything was smooth. It did this upon tearing the front end back down and removal of timing chains. Ohc must have been under spring pressure in turn and rotated when I removed the chains. Tried to spin it back into place but sixes after about 20 degrees of turn in either direction

Are the t8ming chains making any noise?As far as timing chains go there really isn't a maintenance aspect to replace them like a timing belt at a certain mileage.
