Timing chain and cover replacement?

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

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

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.

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.

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

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

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.

This is a complex operation and not for the novice ??

Install the Camshaft Positioning Tool.
NOTE:Slightly loosen the camshaft holding tools to allow slight camshaft movement.

Pre-position the camshafts.
Rotate the LH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 12 o'clock.
Rotate the RH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 11 o'clock.
Tighten the Camshaft Holding Tools to maintain camshaft pre-positioning.
CAUTION:Unless otherwise instructed, at no time when the timing chains are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur.

CAUTION:Rotate the crankshaft counterclockwise only. Do not rotate past position shown or severe piston and valve damage can occur.

NOTE:The number one cylinder is at top dead center (TDC) when the stud on the engine block fits into the slot in the handle of the special tool.
