Running engine without camshaft cover
scoobyis2cool - 10/8/05 at 06:28 PM

Can this be done? Won't oil spray everywhere?

Cheers,

Pete

Depends on how much oil is sprayed around really. Seen it done on a few bmw engines with little oil spray.

God knows what your engine would be like tho tbh

If a cross flow oil will be everywhere, I tried it!!

I'm surprised, as crossflows are OHC and IME you can nearly always run OHC engines without the cover on, at least at idle.

It does of course screw up any crankcase breathing/emissions stuff if fitted which might lead to a rough idle.

???? !!!!!!!

Xflo = OHV
Pinto = OHC

I'll give it a go tomorrow and hope it's ok - will be interesting to watch it all in action even if I do get covered in oil

If you've got a spare cam cover about then you can cut the top out of it. We used to do that on the old opel Cam-In-Head (cross between OHC and OHV) engines when setting up the rockers, tightening the adjusters with it running. (not that you can do that on the pinto!!)


scoobyis2cool - 10/8/05 at 09:46 PM

I have got a spare cover actually so that's a possibility, don't think I fancy sticking any spanners in while it's running though!

A slip of the keyboard! I've run A series engines without a rocker cover, and you get negligible oil spillage unless you rev the tits of it.

No, I wouldn't! On the old Opel engines it was pretty safe and actually recommended procedure, but on them the adjuster nuts stick straight up at you and are tall so a socket sits on them on it's own quite nicely.

Pinto is a pain in the arse to do the adjustments on, the threads are too coarse and the stud always moves when you wind up the locknut!

As I discovered first hand today Especially over the side with the carb, could do with taking it off really

It is written in many places that you should check that the spray bar is squirting correctly by running the engine with the cover off.

I have done this very briefly (about 10 seconds) just to check this.

Oil sprays a bit but if you put some sheets out over the bodywork either side of the motor it will catch most of it

You can get a special spanner for adjusting Pinto tappets when a carb is fitted usually on ebay for about a tenner.

there aren't any just now though - I looked

If you chop the top out of a spare cover with the angle grinder, tidy up the sharp edges, give it a clean and bung it on with four bolts, it'll stop the worst of the oil splash and still let you see the oil sprays etc.


scoobyis2cool - 10/8/05 at 10:12 PM

What happens if the bar isn't spraying properly? Presumably the lobes will wear quickly? Anything more serious?

Pete


Avoneer - 10/8/05 at 10:21 PM

Yep, but turn the engine over only with no plugs in.

Oil will drip from the bar (hopefully) and will not spray everywhere.

Done this several times.

Pat...

Absolutely right the oil should be squirting straight on to the middle of the cam lobes.

Occasionally due to a bit of crud or a bad drilling in the bar the oil squirts to the side missing the cam lobe resulting in rapid wear.

It would be a shame to go and fit a new cam only to have it disintegrate within a couple of hundred miles because the spray bar wasn't checked first.

It's the one major weak point of pintos.

Take the plugs out and spin it over on the starter...

thats the way we used to check pinto spray bars...

Seems like a lot of bother when pinto spray bars shouldn't be too much money . If in doubt replace it , not worth the risk using a suspect item ! cheaper in the long run.

It's not that I think it needs replacing, I'm just interested to see the engine running with the top off and all the valves moving etc. I've had the engine running for a while now with no problems so I don't think there's anything wrong with it, just curious
