Strange Noise From Engine

[phat205 0]

Right Guys,

 

I have an 86 'D' 1600 CTI, It was advertised as a running project. (Ran very badly & rich)

 

All the running problems have been sorted. ie. I put the HT leads on the right plugs. and changed the AFM, now when it gets upto temperature there is a strange squealing noise coming from the drivers side of the engine. I'm either thinking its the Water pump or timing belt tensioner.

 

Just wondering if anyone else has experienced this.

 

Also. I have read some old posts about the difference between 1.6 and 1.9 engines. but.. I seem to have what looks like a spacer block on the bottom of the engine but also have light blue injectors, 1.6 AFM & ECU etc.

 

If it helps i'll clean the bottom of the block up and take some photos.

 

I'm a bit confused as it seems to run ok now. If it was a 1.9 how would it run on 1.6 managment etc????

 

Any help would be greafully received.

 

Cheers

 

Matt

Does sound like the tensioner to me, personally, if you have no history of the cambelt being changed and its been sat for ages, that would be at the top of the list, worth taking the to cambelt cover off to at least see the condition of the belt, last thing you want to happen is a snapped cambelt. Yes a 1.9 will run on 1.6 management just not that great. Does it have the hex headbolts and no breather on the rocker cover as per the 86' 8v??

You see I had this on one of mine, I never did get to the bottom of it (well not yet) but I stripped all the covers of the cambelt had a route around couldn't find it, checked it wasn't the alt still couldn't find it, in the end I narrowed it down to the flywheel area although it sounded as though it was coming from cambelt side. I know this doesn't help but hey, thought id share it with you.

right just been and checked, it has large Torx type head bolts and does have a breather on the rocker cover.

going back to the spacer plate on the bottom of the block... on a 1.6 does the sump fit straight upto the block where you have the casting fins etc, or should there be a flat plate approx 15mm between the two?

Its obviously been replaced at some point, the 1.6 should not have a spacer plate, sump bolts straight onto the block iirc. Is the inlet still mounted on the inner wing, if so worth whipping the rocker cover off as on the earlier 1.6 cams the edges were chamfered, which could help identify it. Only other way would be to measure the stroke, which i think is possible, although not personally done this, by removing the spark plug and finding BDC and turning the engine by hand to TDC. Sure someone will correct me if im wrong on this.

could just be using spacer for the extra sump capacity

Check the stroke of the engine to determine for definate. If you take out one of the spark plugs, use a solid rod through the hole. Turn the engine over to TDC on that cylinder. Make a mark on the rod and turn engine over to BDC and mark the rod again. Use ruler to measure the distance between the marks.

Yes a 1.9 will run on 1.6 management just not that great.

In my experience, so long as you use the complete fuel management setup (ie ECU, AFM, injectors) then 1.9 GTi engines run perfectly on 1.6 GTi management - indeed, the quickest standard 1.9 8v 205 that I knew of (the legend that was Red - now sadly RIP) was running on 1.6 management stuff. I've done a couple of other similar 1.6 - 1.9 swaps since and retained the original 1.6 management because they didn't have any 1.9 stuff, and again, they too worked perfectly - started and idled well, pulled well, and gave good economy.

 

Jetronic management is AFM based, and as such the airflow into the engine is measured directly and it will compensate for the additional airflow - and thus fuelling requirements - of a 1.9 engine.

 

It's having a mix of 1.6 and 1.9 fueling parts on the same car that causes issues, as inevitably the fuelling will be out.

Intersting Ant, the car i drove must have been a turd then as although it idled fine, felt well down on power.

Thanks Any Thats great, I think i have a 1.9 engine and definatley have all the 1.6 managment setup. Hopefully it will run ok.. fingers cross.

 

I'll be a bit gutted really if it is a 1.9 as i've heard very good things about the 1.6 liking to rev etc.

 

Cheers again
