Oil Filler Cap

[poopydog]

Plastic  oil filler cap, push and twist, very stiff.

 

Finally snapped and spins round  in situe.

 

Requires a new cap, however, concerned about removing the old one? force it off with screwdriver tip? what remains  underneath? reluctant to tackle as I dont want the remains  of the cap falling into the engine!!!

ideas  please?

 

 

Thanks guys.

Oil filler cap has always been tight, the only way to release the cap was to grip it with pliers and put body weight over then turn (yes I know which way to tigthen and release ). As it rarely uses any oil and all changes have been done by dealers it has only ever been topped up myself on 2 occasions.

Currently in contact with a fiat dealer who is going to source a new cap, but had the (quick fit  idea of....please dont laugh......).remove the dipstick, attach a small funnel into it and top up this way.

 

Thanks all

Surprised that's snapped? Must have been on extremely tight or no Oil Changes for that to happen?! If its spinning around suggests the thread has gone which in turn may mean you have 'remains' already in the head. Never heard of one of those breaking before tbh. At worst may be advisable to remove the whole head?

The 1st thing to do is to get a new cap

Then drill a 3mm hole into the cap and use a long self-tapper to lock the whole assembly together and unscrew

Remember the 1st thing a mechanic apprentice is thought,

Leftie loosie and rightie tightie :-D

 

P.S. don't worry about small bits of you plastic getting into the engine, as it will get ground up and will finish in the oil filter eventually

Possibly in the worst case scenario, it may be enough to remove the rocker cover

Yes sorry Andrew I meant the Rocker. I guess its only plastic so possibly not too bad if anything has got inside. Still strange to hear though.

Hi,

 

I noticed the oil filler app was super tight on both my deltas and gave up as knew I would break it. Returned the next day I noticed if the engine is warm it’s easier to open, so worth trying that than forcing the cap.

 

Hope this helps,

My oil cap was very tight ......I got it off,but was concerned it may break!

I think that's good advice,re a warm engine....
