Congrats, glad you got is running in tip top shape. No easy accomplishment so big congrats to ya.

What happened with the fuel issue? Did you replace the regulator?

Either way, glad you got her running. And I am happy I could help.

Yeah the fpr was def shot. I got one this morning. Slapped it in and after about 2 hrs of second guessing myself, i decided to start her up. And man was i excited. Thanks man.

OK my car is running like a champ. I finally felt confident enough to fire it up and take it for a test drive. And sure enough it's running spectacular. I just want to thank everyone for all your help over the past couple months. Especially peerless, nomad, and bmw power. $1,700 3 months and losing a girlfriend later....I have my baby back.

Its very possible you hooked up the fuel lines backwards and blew out the regulator. When you reverse the lines, the FPR cannot regulate pressure and you are then at the mercy of the fuel pumps dead head pressure which can reach up to 110-120 PSI. If the FPR diaphragm is weak, guess who wins.

I reversed the lines, I got very lucky and the regulator held, when I loosened the hose clamp the line blew off and sprayed accumulated fuel all over. The regulator made a very loud 'pop'. I should have been more careful. Luckily the regulator survived and I switched the lines correctly and the car started and all is good.

In your case It's pretty obvious the regulator popped and you are forcing pressurized fuel through the regulator vacuum hose into the intake manifold.

Be aware I am not saying your fuel lines are backwards, they very well could be though. You need to make sure at this point.

You got some bad luck dude, my sympathies. But your only a FPR away from getting it running again. Hopefully this will be the last of your difficulties.

Best Wishes.

Tell me about it. So is there any way to get this thing off? It's on there pretty tight.

Ok so i got my timming done. I put everything back togethor. And it didn't start. It attempted tot hen died. So i got out and check everything out. Ok my question the hose running from the top of the valve cover to the lower intake should that be filled with gas? And i def know my air box should not have gas in it either. Also the little hose running from the fuel preasure regulator to the intake also has gas in it. Is my fuel preasure regulator bad? All of my air lines filled up with gas... Man this car is alot of work. If anyone can help me out ...AGAIN that would be great. I am almost sure the F P R is bad. But just want to check and see.

I am also wondering on the exhaust cam should the arrow sit right in between the 15th and 16th link or dead on #15 from the intake cam arrow? That will def clear up alot of confusion i have. In my Haynes manuakl it shows right dead on the 15th. In the pic above it shows it dead on. But in a couple of other pics i have viewed it shows it in between.

Well I am almost posotive i got it. The center bolts are not completely centerd but close. I also put the pencil on the back squares and it's flat. Also the #1 piston lobes are facing each other. Well kinda mora like a triangulaur shape. But it looks just like the pictures i have seen. I have it all back togethor> I have to wait till tommarow to fire it up tho. I cut my exhaust to get the manifold back on on. So i gotta get some pipe to fit it. I wish i could get some pics on here but i have not been able to locate my camera. Thanks for everyones help. Maybe someone can post a pic of what thier back cam suares look like with a pencil across the, and maybe a frontish pic of thier #1 piston lobes. That would be great.

Ok well after messing with it some more. I am kinda back to where i was. The back squares are def flat and the front lobes are def looking in the right spot but the holes are not lined up. I am at a loss. I am wating for my girl to show up so i can get my damn camera. Will take some pics soon and send em your way thanks again.

Ok so it looks identical to the pics posted above. I even got a second opinion, just cause my eyes hurt from looking at this all day. Thanks for your help. What do you mean look at the bottom end?

I would love to take some pics. But my girlfriend has stolen my camera for the beach. But my head looks just like your pic. Only sideways. And what do you mean by pointing each other? Slightly pointing at each other? Or directly dead point of lobes facing at each other? Like your fingers on each hand facing each other?

Ok i just moved the cams a bit and the holes lined up good. I am not sure if i am tooth of. It looks identical to the book. It's hard to tell with pics you posted cause they are taken off to the side. There is still a noise when i turn it. Like something is under preasure. I am going to mess with it a little more hen i will get back to ya.

for reference:
http://www.esatclear.ie/~bpurcell/318istimingchain.html

Cam gear bolts are not centered, when it is all put together right they will be centered.

Use the trick I posted to hold your cams with the rear flats even. In the photo your exhaust cam is off, not flat, it looks a bit anti-clockwise and the intake cam looks a tiny bit clockwise, see how it's not even with the valve cover mounting surface?

All you have to do is take off the cam gear bolts and let them slide off the cams, then realign. I did the same thing you did the first time and puzzled over it, then adjusted it, tried again and it was right.

What is really important is if you have the cams themselves in the right position to begin with: front lobes pointing towards each other


When the cams are in this correct position
and
When the flywheel is at TDC
and
When the flats of the rear lobes are clamped firmly in a perfectly flat position
and
The tensioner is not applying force to the chain
then
The cam gears will go on in a perfect alignment with the cam gear bolts truly centered in the cam gear elliptical holes.



15 rivets inclusive from arrow to arrow is correct, but remember that you may be one tooth off on both cam gears if they are not lined up correctly.

BTW
The head looked nice to me and the block seems ok. Not sure if you bent rods as mentioned before from having the coolant in the cylinders. Other than that I hope it goes well.

Post pics when you get it all timed up.


EDIT:
I think you may just need to loosen the cam gear bolts, reposition and lock the cams and you may be good to go.

So you want me to loosen bolth cam sprockets. Readjust my exhaust counter clockwise. Then adjust my intake cam clockwise a hair? When i put a pencil on the cam squares it looks straight. And should i turn my sprockets a tooth clockwise or counter clockwise?

The cam gear bolts do not look centerd, do i have to tear it all down again to get those centerd?

15 Links apart:


Right timming gear:


Left timming gear:


Cam square lobes flat:


Cam Lobes Flat:




So here is where I am at. Here is where i seem to always fuck it up. So if any one can see soemthing wrong please tell. Me. lso when i turn the crank by hand, i feel some preasure in certain spot when i am turning it.

I have put the head on. I tightened all the head bolts down to 22 ft/lbs then an additional 90 deg and then an additional 90 degs. I put a 8mm allen key in the flywheel at tdc. My cam squares int he back are flush with each other, i put a pencil on them and they are flat. I am not sure how they sit in compoarision to the head, But the cams are flat with each other. My sprochet wheels in the front on the cams are 15 links away from each other intermideant.  Now from my understanding this is correct and how it should be?
