Everytime I give the car a bit of a thrash the oil cap tries to jump off which eventually causes my car to cut out on idle if I dont push it back down!

I have been told I need a breather system...is there anything else I can do in the meantime to try and prevent this?

 

yes tape it on

 

I take it its a cvh
Try a new cap as the rubber gets melts some times
That or a breater sytem as it probley breathing aa bit heavy

Or as LEE said tape it on

 

hope its nothing more serious crankcase compression could be worn rings nasty business

 

its not rings the car runs perfect and doesnt smoke

told u to get a breather on it

 

Easiest thing to do is clean it all up inside and clean where it sits on the rocker cover.

A few times round with some black insulation tape and jobs a good one it will stay on.

Get a breather kit from one of the traders.

70-80 quid will see you with a nice 2nd hand bailey breather and prob the pipes to go with it.

breather system is normally a cover up for ring damage.

hope its not the rings - try the breather - definitely the cheaper option!

 

I got a nice fusion breather pot thing second hand, mines not popped off since!

 

if the breathers are not blocked/cant cope your rings are most deffo fucked mate.

 

well worth fitting a breather imo. but first get a new genuine ford cap,
most 'pattern' ones don't seal aswell, an if your cap is a bit old, as said above, the seal gets poor.

 

Yeah Tape it.

 

Stu told me the best thing to do is get one of those special bufty shiny caps that have the screws in them to fix them on real tight. He just loves these and wishes that Motorsport developments had thought of these first.















JOKE!!!!!!! before Stu sends someone round to kill me! If the cap is in good condition, then as other people have already said there is a good reason the cap is coming off.

 

I tried to kid myself that a breather system was all I needed to stop the cap popping off [even the dipstick shot out when it was having a power run at Engine Advantages ]

I put a bailey system on tho and it was ok for a bit, but just hiding an underlying problem.

Which is why my bottom end is now in bits

Get it looked at properly, get a compression test done [just for peace of mind if anything] befoe you wind up doing more damage than just a set of rings [Like me ]

 

cable tie the cap the cable tie to wear the car wire thing holds it on and pull tight, job done u till meltdown

 

My kinda man

 

my xr2 was doing this so went to ford got a new cap did not blow of after that o and if your running more than 10 psi get a breather

 

well thats what we done on the way to central day, was having a laugh and the filler cap fell off, as we had a spare we came up with the fix it solution, rebuild time, fook no, grab the cable ties and we will fix it perminantly !!!!!

melted 2 pistons and a plug tip looked not too good on number 3 on the high speed fun on the way back

only minor meltdown though

 

Not on the Cossie Ginge?

 

Most breather systems dont use a large enough exit pipe blow by will always happen with 25 psi plus,always use a large exit breather.

Use a bit of Jim Galbally patented gaffa tape...
