Hey guys this saga continues it drives but like a old truck very little power. When you take off it takes off slowly and pops and cracks the air cleaner box and snorkel. It also stinks of petrol and is using heaps of juice. Could this be the O2 sensor?

Cheers

Sounds more like timing or one of your timing belts are off by a tooth

if it backfires thru the intake then yer does sound very much like theres something amiss with ur timing

I played with the timing belts the passenger side was spot but the drivers side is another thing. It was slightly about 1.5cm past the little cut out but when I moved it back and put the timing belt back on the teeth on the belt pull it back 1.5cm before hand. Not sure what the deal is there but I left it put it back all together and so far it seems fine just gotta take it for a spin and see how it goes. The reason I think its not lining up is maybe because the covers have been replaced with ones out of a carby model as the MPFI ones where melted to badly to be of any use. Not sure if thats what the prob or not. Cheers for all the help guys

if the camgear was a tooth out (1 or 2 wteva 1.5cm relates to lol)

then the carwill run liek crap and depending on where the Distibutor was set then it very well culd hold a valve open when it sparks so that culd mean a backfire thru the intake.

also if the covers where melted badly u may want to check the belt thoroughly for any damage if it wasnt replaced yet.
serious heat wont do the belt that good.

The cam gear - its very important to have the tension on the "pulling" side of the belt so that when it's tensioned the cam gear doesn't move off the mark. If you're one tooth out you will notice a difference. I usually find that my cam mark (on the cover) and the cam gear mark doen't line up exact, usually sits to one side, even with new belts...

Also remember with your cambelt timings when you set them to make sure you turn the crankshaft one rotation between the setting of the cam shafts. Otherwise the engine will only run on one bank of cylinders at a time (I made this mistake and it took me 4 months to work it out...).

If the cam cover had been melted you may have more issues that you bargained for. When i got my L the carbie engine had done a head gasket - the cam covers came off and looked like they had candle wax droplets on the back of it. As it turned out that engine was dead - cracked cylinders.

If you haven't done much to this block except change the head gaskets i'd be checking your cylinder pressures and blow by, just to be sure that everything's good there.

Defenitely follow up on the cam timing - use a mirror if you can't see it on the passenger side (and at the same time check the driver's side - should be 180 degree's difference).

Ive been bitten by that before, quite easy to do, but thankfully easy to fix.

I second having a second look at your cam belts

Hey guys I have fix the pain in the butt. My now EX-Mate 4th Year apprentice motor mechanic had put the leads on wrong thus he is now my ex-mate 3 months this has gone on for what a tool. But its back and a valuable lesson learn't don't trust mechanics they know jack shit when it comes to Subaru's.
Thanks for all your help I am so happy I have been doing the happy joy joy dance for the last 15 minutes.

That's awesome Kris (that its fixed). Hope the MPFI is everything you hoped it to be, I was pretty happy with mine and can't wait to get rid of the carbie that i'm running atm...

Its always something simple...

Happy 'rubin

Ha ha

Something so simple caused so much grief.

I had problems for ages after my new turbo install. Engine has less power than before. Turned out the fuel pressure gauge was inaccurate and i had actually set my fuel pressure too high. It was the last thing i checked

Good to hear - I have been following this with a lot of interest. It is always the case in that it usually is the simplest, least expensive solution.

I have a mini that I pulled down and rebuilt(the engine anyway...)and when it went on the dyno, wasnt working. All manner of things going through my mind and went sstraight to the mechanical problems...took me weeks and just by happenstance I was replacing the distributor - found out the distributor was inserted 180 degrees backwards(super retarded!!) hence it was only firing on one or two cylinders at a time and at random!!

Again I am so glad you got it sorted - even after you bashed the crap out of the cat!!
