yeah, i had already looked at that but it didnt appear to help me. where it shows relay k28 it also shows 2 fuses next to it, mine has 3 fuses next to it. the diagram doesnt show what the fuses protect either, thats what i need to know.

managed to dodge the weather today and do a little, the car is timed spot on, but still spits back into the inlet when turned over. i had it suggested that the cat could be blocked and as the gas has nowhere to go then it would go back up the inlet so i have now disconnected the exhaust downpipe to manifold but it still does the same. i am now contemplating taking the head off again to check whats going on but if anyone has any suggestions to try before i do that then they would be very welcome.
just a question though
i took the heads off when i did the engine change, and as you are aware you have to take one cam out of each head to get to the bolts, is there any way that i could have fitted the wrong cams to each head. is this possible?? if it is would this cause what i am experiencing.

been out there for an hour tonight, the plenums off, the upper inlet is off and the 2-4-6 bank rocker cover is off. there is nothing in the top of the cylinder head and i have had a magnet pen inside the cylinders and nothing is inside them either so i can now rule that out. i have turned the car over as it is and it pops out from all three cylinder on that side. if i take any one of the spark plug out (so no compression)then it doesnt pop from that cylinder. if i take all three out then it doesnt pop at all. the 1-3-5 bank sounds perfectly normal so im ignoring that completely for the moment. now, fom my knowledge i would say one of the cams is slightly out even though i have set the timing again, its too dark to do this again tonight so im gonna have a crack tommorrow again when i get back from work. also i have a high power led light which i shined down the inlet tract while each set of inlet valves were closed, i peered into the cylinder through the spark plug hole and i could see no light at all, not very scientific i know but i think as best i can that the inlet valves are seating correctly and none are bent. obviously i cant do this with the exhaust valves but as its firing back into the inlet im assuming the inlet cam is wrong. please correct me if you think im wrong.
lastly, so far your help guys has been massivly appreciated, please keep it coming, i dont think you realise how much you are helping me, john.

this is the replacement engine, the original one got chucked. it was ran around by my brother in law for about 6 months before i took it off him and it was running perfectly. i took the engine out, done the headgaskets, new cambelt kit inc roller,etc. the put it all back in.
it starts first turn of the key, but it has the symptoms of backfiring into the inlet manifold. although its not constant with the engine revs and this is what confuses me. i have checked the timing and im gonna take some pics in a bit and post them on here so you can see where the marks are. i might be wrong but it only appears to do this out ofnumber 4 cylinder and when you put you hand on the plenum during the first couple of minutes of running it is definetly a damn sight warmer on the side nearer the egr than it is on the iscv side.
i have managed to get some seals today from vx, is ti worth me fitting them yet and trying or not, john.

it is a 1994 engine in a 1998 car, not ideal i know but in a rush to do the job the knock sensor wires were cut and spliced due to different shaped plugs. if i put my hand on the plenumroughly over cylinder3 (which is where the inlet for cylinder 4 is) then it feels like something is hiting it everytime i hear the click, its deffo related to the inlet/cylinder area rather than pulleys or the front of the engine.
the multiway connectors are fine and i will double check the only earth i disturbed when doing it (the one to the engine itself.
would early sensors on a later ecu make a difference as i think i still have the original sensor that i took off the 1998 engine before the tat man took it.

good question about it being in time with the engine revs, NO IT DEFINETLY ISNT. its completly as it feels, just random, but more so when cold and less noisy, but still there when warm. like you said, changing the seals is cheap so im doing that as soon as i get some, (next day or so)

you sure!!!! even with the plenum off its popping back up the inlet!!!
can you give me the part numbers for the 6 seals so i can get the right ones, how much are they likely to cost , thinking about it that plenum has been on and off about 30million times in the past few months.
ps. ronnie, this is still part of the problems from when i phoned you months ago, john.

ok i done a lot of work on this car and feel im so close that i dont want to give up now. basically i changed the engine in the car (2.5 v6) and the car starts and runs BUT, there is a quite loud clicking noise at the top of the engine. if you put your hand on the plenum while its runnig then you can feel as though something is hitting it inside. it also sounds like it is misfiring slightly. the noise does seem to drop off a bit and idle smoother as the car gets warmer. i have taken the plenum off today and pulled the two purple relays in the engine bay fuse box now when i turn the car over you can here it pop back up one of the inlet manifold tubes, number 4 i think. i have borrowed the timing kit of someone on here and its as good as its ever going to be so i dont think its timing. its also had new plugs and leads.
the eml light is on constantly and the codes given are
12 (start of test)
21 (throttle position sensor - high voltage)
31 (crank sensor)
57 (idle speed control valve - interuption)
94 (hall effect sensor - high voltage)
129 (this isnt in the topbuzz list but someone said it was the egr valve i think)
145 (immobilizer - incorrect signal recieved)
im not sure whats causing these problems but there are no plugs disconnected that i can see

the vaccum pipe is the long thin pipe i believe that goes under the cable tray to the ront of the engine then joins to a much larger pipe that goes between the idle speed valve and one of the air intakes from the multi ram.
the crank pulley holes are slightly offset so they bolts will only go in if the pully is in the correct position.
i made the mistake of setting the engine totdc then putting the mark on the pulley at the bottom but it doesnt go like that, the mark sits at about 2 oclock to line up with the line on the engine, hope this helps, john.
