redone engine seals now no compression

[deek1992]

I have stripped all the seals off my 4efte. cleaned the carbon build up off of the valves renewed all gaskets and seals. car now wont start. compression test shows up no compression atall as did the wet test. obviously meaning the piston rings are ok. timing is bang on tripple checked this lol.seems as if the compression is being lost back through the inlet side of things. im thinking possibly a valve problem and i am going to remove head on Friday. but if anyone has had a similar problem and it is something stupid then let me know.

Cheers derek

Lost comp on all 4 cylinders?

[yaristurbo]

cams timed up 100%?

what did you use to remove carbon off valves, did they go back in same order?

and is your tool 100%?

Used a wire brush cans are defo right. And checked comp tool against another car so that is fine too. All valves and buckets went back in in same order

[funny onion]

Did you lap the valves back in?

[deek1992]

Yes but only with fine stuff to clean the seats up a bit.

You sure the timing isn't 180 degrees out? I would double check.

[deek1992]

Cylinder one at tdc. Cams can't be out as marks are lined up.

[Danza V]

Sounds stupid, but your headgaket is on on correctly ?

[deek1992]

Yeah. As far as I know it can only go on one way

[AdamB]

The headgasket can go on two ways. But it won't affect the compression, you'll just have a monsoon of an oil leak.

If you've lost compression on all 4 cylinders then it's unlikely to be something you've done with the head, that would be very unlucky. I still reckon the timings out 180 degrees.

i dont understand how the timing could be out if the factory marks are lined up on the cams and cylinder one is at tdc. Its mind blowing lol. its gonna be something very stupid. i will let you guys know WHEN i figure it out haha.

[morgey]

Youve timed it up on the 4e timing marks on the cam pulley?

Not sure if its possible but its deffo a 4e belt? Not a 5e one. Id assume they are longer.

[deek1992]

If it was a longer belt it would not tension up. And yes definitely the 4e marks. I'm a mechanic so know what I'm doing but just wondered if there was something that may have happened. It's probs something silly. Will find out soon when the head comes off lol.

[morgey]

Yeah not doubting your ability mate just going through the motions.

Like I say im not sure on the belt just a suggestion lol

[Danza V]

Weird one. I'd go with Adam and say its gotta be timing.. Unless the camshafts have beeen put back in not lined up :/. Very strange :/

That's fine open to all suggestions lol. Yeah I seen that gt turbo thing and had a look. Will triple check it all tonight.

It's the only real thing I can think of, unless there was something you done with the head, but I doubt that.

[neilsmith]

did you remember and put the flux compasitor back on the head? if i was to guess what is wrong i would say its that x
