#51 in the picture is the oil pressure sending unit, remove it, and install the gauge there.
if your oil pressure is good, then remove the valve cover and loosen, and remove the cam caps one at a time, and remove, then reinstall, with slight pressure pushing them toward the front of the vehicle, when torquing them back down.
where the black arrows are pointing,
tighten to 89 inch pounds. while the valve cover is off, shine a flash light down the front cover and look at the timing chain guides, and tensioner to see if there is any wear, or damage showing....
I did not accept this yet because I haven't solve the problem yet.
I had open the valve cover and the timing chain and tensioner looks good. I did notice that the plastice guide had a chip. It didn't dook like it would affect the timing chain. I closed everything back up and turn on the engine and it's still making the knocking noise. It's also throwing a P0174 code. What's next?
Fuel pressure is good and there is no vacuum leak. Another thing is when the car is park and I press on the gas, it gets to about 3k RPM and bog out. It will star to shake, but when I drive it, there is no problem getting pass the 3K RPM. Is this usual on a Lincoln?
Will this cause an oil leak?
have you checked the crankshaft dampner? to sse if it is coming apart? also what shape are the motor mounts in? what weight oil are you putting in it?
So all the valves are install at the same height? I know in the Honda each valves has a different height.
Do you have any good pictures of the valves, both set?
in or out of the heads? i will have to look around, but let me know specificly what you need, thanks,
you can search ebay for the ford/rotunda tools, let me get the #'s. do you have the head off?
here are the special tools to use, once the head is off. be careful when removing the cams, loosen the caps evenly, so the cam does not break.
I had the valve cover off only. I already got everything back together and took it to get a diagnostic check and they said that it's showing miss fire on cylinder 1 thru 4. I don't think all the cylinder would go bad at the same time. I have just replace coil #1 & #4.
Let me restate how the knocking is made. When the car is cold during idle, no noise is heard. When the engine gets hot, the knocking noise is heard during idling and it gets lounder as you step on the gas. When the car is in motion and goes about 30mph, there's no noise at all. The car still run smooth. If I need to take the head off I will do it. It's a big job. Do you think with your help, I can do it?
Is there a way to check to see if it is the spark knock? I also saw the timing chain plastic guide broken when the valve cover was off.
If the timing is off, how do I adjust it and is there any sequence?
well, spark knock is actually something that is caused by carbon build up on the pistons, that gets hot during combustion, and causes pre-detonation=noise=spark knock. you could remove a spark plug and shine a light dn in the hole and see if you can see black build up on the top of the piston.
ok, now, with the broken timing chain guides, your timing could be off, ...i thought we had already discussed that eariler?? back on 12/14? you will need to take off the front cover, and replace the timing chain guides, then retest
I did mention it but we didn't really talk about it. I'm guessing the timing chain will have to come off in order to replace the timing chain guides, correct?
