[dac69er]

keep finding differing specs. does anyone know definitively what the clearances should be for a stock engine with stock cams etc?

so far found these:

4EFTE manual states:

Intake = 0.20mm plus or minus 0.03mm

Exhaust = 0.30mm plus or minus 0.03mm

When i rebuilt my head a couple of years ago i used the specs on here as posted by Texx but i can't confirm either way i'm afraid.

My 5E manual says :

Exhaust = 0.31-0.41mm
Inlet = 0.15-0.25mm

When cold.
Uses the same head as the 4E, so will assume these are correct as GP82 has said also.

Thats the figures I use, larger gap for the hotter exhaust valve, taken from a 4E manual.

i will go with the consensus i think

Since shims only come in 0.05 steps, you wont get it bang on a figure, from measuring them around their circumference, they dont always wear square either.

Its a head melting job, before you start measuring anything, if the engine is out and you have had the shims and buckets out, give the cams at least 10 rotations to settle everything down where it should be.

engine is out as i have rebuilt it and head has had some machining work. made my measurements and measured all my shims to determine what shims i actually need. 4 of the exhaust ones were spot on which is a good start

found the clearances on a sticker under my bonnet. 0.2mm inlet and 0.36 exhaust. my feeler gauges only measure in 0.05mm increments anyway so am working to that and trying to get it as close as possible.

will fit the shimes tonight and re-check. hopefully i will get it right first time so i can button the engine up ready for fitment

For a 4efte the exhaust is too tight, dont make the mistake i made.

turbo is larger exhaust gap
