4age Problems

[Jedi]

Um actually I didnt, got it about 6 months ago from a friend of a friend of a friend of a friend. Car was in Gosford NSW. I know it wasnt on ebay because I was checking it when I was looking for one.
Im somewhat regretting buying it in that Ive owned it for half a year and driven it a whole 200m. Getting offroading withdrawal symptoms.

your gonna have to check it for your self i think That way you can atleast establish what you are dealing with .

[Jedi]

Diggity.
Well, this car just keeps on hating me. After biting the bullet, I pulled the engine down and gave it all new gaskets & seals, gave the head a machining, had the cylinders honed (they still had the original criss-cross pattern on them), and put new rings in. I found one of the rings on cyl 4 was stuffed.

After bolting it all back together, the problem of the fuel pissing out the intake under throttle is still there and if anything, is worse.

Its so bad that fuel is pushing itself up past the plugs and even up past the cam cover bolts When the engine is shut off and I either open the throttle at the TB or pull a plug a little bit of smoke comes out which I cant see being a good thing.

The only upside is that its straight fuel now, no oil, which I guess is something.

I cant work out what the fark the problem is other than to surmise that it is most likely in the head as I didnt have this rebuilt when the engine was in bits but it seems a bit extreme for stem seals.

Any ideas?

How does the car actually run now besides the fuel pissing out ???

[Jedi]

It only runs for about 5 seconds until the fuel starts coming out then just stutters and dies. In that 5 seconds it runs sweet though


It will also only start if the throttle is wide open when cranking if this makes a difference. No throttle or half throttle only produces stutters and "almost but not quite" efforts.

Hmm are the correct injectors in there?

I suggest going to wreckers and grabing more injectors,fuel pressure reg and dampner. All easy to fit in ur pocket.

Wack them on and try that.

[Jedi]

1000% correct injectors. Put my old injectors in and same problem occurred.

As I said in a previous post Im not sure if the FPR is the culprit as no fuel leaks out of the vac line on the FPR. Doesnt this signify that it is in working order?

Not too sure what you mean by "dampner". School me.

[Cuzzo]

Well firstly fuel doesnt flow anywhere near the vac lines. The vac lines only carry air or more so vacumming air.

So that cant prove if its buggered or not. I was trying to find a picture of the dampner. It sits ontop of the banjo bolt fuel feed. (i think)

If the diaphram in the FPR is ruptured, it could be leaking fuel into the vacuum line.

Well i stand corrected.

[Ben Wilson]

Well i stand corrected.

It would never have occured to me until I read your post...

[Jedi]

I was taught that if an FPR is buggered, pull the vac line off and fuel comes out. Could be wrong though. Might change it anyway, like you said Cuzzo, they arent expensive.

Incidentally, Ive started the car using two different ECU's and the problem is the same which rules out a computer failure. I hope.

[ganador]

is it firing in the correct order. check that its firing 1, 3, 4, 2 and that the dizzy isnt 180 degrees out, if so take it out and turn it 180 degrees then put it back in. Maybe the oil in the cylinders could be coming from the valve stem seals. I had all your simptems with my 18RG and new stems seals with the rebuilt head and corrected dizzy fix it.

[Jedi]

I did think of the stem seals but there doesnt seem to be any oil in the cylinders. Just fuel, unlike before when I had dodgy rings.

Timing was one of the first things I thought of too (great minds hey) but it is all kosher. Im leaning towards doing the stem seals though. At this point Im willing to try anything......

Well sounds a little like you have a sticky intake valve, did you spin the cams and check that when the head was off??
