Basically I was replacing my S1 PTU with the S2

 

everything went alright except that I didn't bother putting 2 bottom bolt/screws when I put the PTU on, the 2 bolts on the top I felt were more than enough to secure the PTU well.

 

anyways I started the car, car started fine but I could hear stupidly loud screeching sound, and when I say loud I mean REALLY LOUD!, I couldn't even get near the engine bay to investigate.

 

After further investigation I found out its the 'Driver side timing belt cover' somehow fouling and making the noise, the noise eventually eased up but was still loud enough to annoy

 

I took the PTU off again and this time tried bolting all four bolts, well surprise surprise the top 2 ones I put on are cross threaded so they come out a bit and then start spinning freely and now won't go back in either.

 

Right now the PTU is held by the bottom 2 bolts the top 2 bolts are halfway in

 

the car isn't making the screeching noise anymore, but does if I push or play around the cam cover

 

so the question is.... whatever is fouling behind the belt/cam cover would it be serious? I dont know where the PTU bolts actually go into behind the cover, these PTU bolts are pretty long.

 

how easy is it to remove that side of the cover? and does anyone has one? lol

the ptu is held on with 4 bolts as you state, i have relocated the ptu to behind the passengers headlight, of the two bolts that are cross threaded, can you get some long nose pliers under the head of the bolt and remove with socket?

i think i have a spare set of cam covers but need to check tomorrow.

Could be serious if it's the Timing belt rubbing!

The bolts enter a fixed captive nut in the plastic of the cambelt cover, if the bolts you have used are too long or over tightened/cross threaded, you will have pushed the captive nut out of the molding and will likely be touching the front of the exhaust cam pulley. You should be ok once taken out, but i would remove the ptu from the cover and re route under the nose panel. Plenty of cable to do it, you will just need to cut some of the tape/heatshrink to take out the water sensor feeds.

Groover, I think you're right, I didn't use long bolts, used the original bolts and they came out easily enough, it was an extremely niggly job though.

 

I can remove one of the cross threaded bolts of I wrestle with it enough, the other one is a bit too in to wrestle out, so i'd imagine if I remove the cam cover I can just replace it with a new cam cover and re-locate the PTU

 

at the minute its not rubbing at all probably because the bottom bolts at the minute have possibly angled the top cross threaded bolts away from the pulley it was screeching against.

 

is the cam cover easy to remove? I had a quick look at it before it got dark, there is one cam cover bolt behind the hard water pipes which is a mystery :/

Unfortunately the water pipes need to come off to get to the bolts behind it, shite design i know lol, if you do then get some gasket sealant for when you put the pipes back on. Intake pipes off too. Its not hard, just more time consuming than it could be.

So would you reckon its worth taking the cam cover off to see if all is well?

 

Its not fouling at the moment since I managed to pull back bit of the top bolts.

 

Just curious if its worth checking the pulley for damage? I think the pulley will be fine unless you guys tell me Nissan made it outta cheese lol
