Seven months ago, I crank up my car and it was making that flapping clanking noise like when a timing belt tension-er is loose (knew that from experience with another car). I instantly turned it off and left it alone until I started the break down a few months ago.
Despite my intuition, I started the diagnosis by looking at the pulleys( took off wheel, serpentine tension-er, serpentine belt, etc. It was super cold so I put everything back and the car would not crank. A couple of weeks ago, I went back to diagnosis mode and checked all the start-up issue points.
Finally, I checked under the top cover of of the timing belt: it looked fine(no slack). I decided to just take everything off to get to the bottom cover. Unfortunately when, I pulled the crank pulley the crankshaft sprocket came out too. It was at this point that I discovered that the bolt on the tension-er arm was broken. I then easy-outed the bolt, ordered the new bolt, pressed the tension-er pin back in, put belt back and bolted everything up.
I then, pulled all the plugs turned the crank to TDC (belt on): it was literally less than 10°off. Here is the problem, the left hand cams (flywheel intake and exhaust) are at TDC, but the fight hand cams are off: one by like 10° and one by 15°. I have checked, and piston one and four are at TDC. I even took the belt off and loosened the right hand cam caps and tried manually turning them: scared to force them.
I do not know what to do at this point. Could the marks be off? Is their a way to check if the last mechanic just marked them wrong? Did I do something wrong? Please help!
