Hey guys I am new here but have read Alot on these forums.. So here is my problem and hope you can help..
Just had timing components redone. Now there is a rattle/knock only in gear at 1900-2200rpms. No noise in park throughout all rpm ranges. Runs good no sign of missing. Here is a list of what was replaced..
Rear guides
Rear tensioner
Rear Cam sprocket
Front Guides
Front chain
Front tensioner
Front Cam Sprocket
Primary Guides
Primary Chain
Primary tensioner
Primary Sprockets
Balance shaft guides
Balance Shaft chain
Balance shaft tensioner
Oil pump
Water pump
Intake gaskets
Rear main seal
Plugs, wires, hoses, thermostat, pcv valve, 5w-30 Mobile 1 synthetic oil and filter.
Rear chain wasn't replaced because he said he didn't want to take head off and jackshaft bolt was known to strip easy.
Now after install I took it back to the mechanic about the knock and he tore it back down and put another set of tensioners all 3 (front, rear, and primary) from Ford.. Still has the knock/rattle at those rpms when driving..
What could this be? Did he not do something right? I can't really pinpoint where the sound is coming from.. Its is pretty loud and wasn't making this noise before the timing rebuild.
Could it be out of time? Even though it starts and runs fine?
Crank sensor? Knock sensor?
Put Iridium plugs in at the same time.. Could it be spark knock?
Also seems to be getting terrible gas mileage maybe around 12mpg..
Supposedly he did a compression check and driver side banks where around 165 and passenger side was about 135... But Idk if I believe that.. Mainly because he was saying the exhaust valves where probably bent prior to repair.. Which is why he did compression test to "prove it"..
Needless to say the vehicle was running fine beforehand with only the typical timing chain rattle occasionally. Now it's making this noise and he apparently doesn't know what it is or how to fix it..
What do you guys suggest? Also another note.. No CEL lights or codes.. When using the torque app the timing advance at idle is showing around 18degrees but while driving it shows up to around 40 degrees.. Is this correct?
Thanks in advance to anyone with any help, ideas, or suggestions.. This has really become a pain in my *** and getting very costly.
Feel like I have been screwed
