PVC in rover tappet covers
When you drive with purpose, spiritedly , the pcv valve shuts under low vacuum and blowby gasses fill the crankcase- Facebook entry from Lethal

- Let it breathe!!
- After watching Holden V8's spit there cork gaskets and oil everywhere at the track, my P is getting a big hole to stop crankcase pressure causing leaks.
- Neville Humpherys
- I think I'd run it threw a catch can.
- Lethal Haberl
- I did think about it , but for the street , the big blue catch can on top of the carby will do����
- Neville Humpherys
- Suppose it depends how heavy the motor is breathing.
- For the street it'll be fine, but for the track i reckon you'll need a can.
- Andrew Klute
- Sounds like a rebuild is in order if it’s breathing that much
- James Leonard Garrod
- I'm not sure of the laws in other states but it is illegal to use an aftermarket catch can On a street car in NSW.
- Tim Bentley
- Can you describe what your doing here Lethal Haberl ?
- Lethal Haberl
- When you drive with purpose, spiritedly , the pcv valve shuts under low vacuum and blowby gasses fill the crankcase, the gases exit the crankcase via the little tiny hole in the rocker cover, enter the carby and get burnt.
- It's my track experience that the hole needs to be large ( preferably on both rocker covers) and I am using a Holden breather / filter to put the gasses back on the outside of the air filter assembly .
- The crankcase pressure is lowered and the engines leaks are reduced. Cheers
- Tim Bentley Lethal Haberl
- love it, thanks mate.
- Will do the same on my p and dolly sprint.
- Adam Woodwards
- Something to watch for on rover rocker covers.
- The std p76 ones vent really well from the oil filler cap, the rover ones dont.
- Neville Humpherys I'll have to find the photo of the valley we destroyed by not breathing the block enough.
- Adam Woodwards
- I spat the front crank seal out and pushed the valley cover against the bottom of the inlet manifold ��
- Neville Humpherys
- Yep inverted the valley at Lakeside.
- Ryan Ford
- Is this only under extreme conditions?
- I'm running Rover rockers and don't fancy blowing seals or valley covers!
- James Webb
- Blowing trannys, blowing seals. OMG lol.
- James Leonard Garrod
- Arr, let 'em go - they're just venting......
