1600 OHV - dipstick and oil separator unit

Post by JamesF » Tue Dec 19, 2017 9:18 pm

I put a jubilee clip round the bottom of the dipstick tight again the shoulder to stop oil leaking out. The oil emission unit has an 'O' ring on the bottom and a rubber seal to the valve. Both seem to be reasonably secure and fair condition.

Anyone else had any oil leaks from these. I don't recall any with my Escort years ago and did about 150k. I was thinking of putting some gasket sealant around each.

Thing is it seems that the oil leaking has found its way in through the bell housing as my clutch has just gone. NOT slipping but simply can't get into gear. Release arm not bent, thrust bearing ok and cover plate springs ok. Can only think that springs in the lining have broken.

far worse though - no go means no job.

Doesn't sound good if it's leaking from the dipstick, PCV valve & rear crank seal - it's not suffering from excessive crankcase pressure due to worn rings / bores is it ?

After a cold couple of days I found a clutch wasn't required just a new cable.

The rubber seal on the oil separator was a bit weak which I replaced with another fortunately finding I had a spare. Tightened up the clip on the dipstick and I'll see if that stops leaks from there.

But what I also did was to remove the feed into the induction manifold. I don't follow the logic of Ford of providing the engine eating it's fumes with the oil separator feeding into the induction manifold and yet allowing the oil filler cap to escape to atmosphere. On my Escort 1300 the fumes fed into the air filter. Feeding into the induction manifold is actually sucking with about 20 psi vacuum. I took off the induction manifold nozzle and blanked it off a 1/4 NPT blank (no servo fitted so no loss). Connected the oil separator pipe and oil filler cap (having fitted the one with a nozzle) into a 'T' piece and then run a pipe to the clip on the back of the o/s engine mount bracket for venting (ideally one should fit a oil catch tank but there isn't the space. This clip I would assume to be for the clutch cable to avoid snagging on the steering joint as it rotates (just got a cable tie to avoid that at present until I get hold of a correct length clutch cable).

When tuning I found the idle far better without the dirty oil vapour going into the mixture.

Oops - I mean 20 ins vacuum
