Hi guys,

having a minor problem with my rs,it stalls randomly,and if i rev it with a bit of grunt and let go, when it drops to 1k it just cuts out.

been told it could be a vacuum problem? or blocked breathers?

was thinking of getting a piperx crankcase breather also.

the elbow coming of the left side of the rocker cover is also a bit of a weird shape.could it be this causing the problem?

any help/advice much appreciated

breather hoses split, or the wrong type dump valve are common

 

I was gonna say the same as the above.The mfi engines need a good vacumn or they will just keep cutting out.

 

dont think any pipes are split and my dump valve is a bailey twin piston red one which is fitted properly.


the circled bit in the pic is what i have told is a bit of a funny shape,could this be causing the prob?if so how do i sort it .

theres also the breather on the other end of the rocker cover, on the right.
This one was more of a problem on all 4 of my cvh engines.

 

Well if it doesnt look right ie if its kinked it might be causing the fault.Do you have any better pics of that pipe.

 

sorry not got another pic of the pipe and the cars in the garage 15 mins up the road .
its sort of kinked in the middle,any ideas where i could get a replacement from?or another scrapyard jobby

 

I always thought they had these little pot thingys (techincal i know!)


However Mine has just started doing the same thing and after an hour of checking every vacuum pipe twice, dip stick etc etc, it tunrt out to be a tiny split in the bottom brake servo! Which was obviously sucking in a bit of extra air, enough to make it stall.

 

Your an absolute genious!!!

I been suffering from same symptoms, tried everything and Im pulling my hair out and come to think of it a strange hissing noise is coming from my servo!!!

 

Take the litle black pipe off that comes from the servo into the inlet plenum. and stick a finger in the hole in the plenum, then start the car, should run then. ( not very well obviously )

 

Sometimes the diaphram in the dump valves leak too.

 

right well,i do not have the same as what chop shop has and after researching on the bay,ive looked at another 4 rs with it.its the crankcase breather,wondered why when i looked in my haynes at it and looked on my car i couldnt find it,obviously as it doesnt exist,just like i didnt have a thermostat,pikey bastard who sold it to me
