Hi y'all can anyone tell me what exactly the three holes are for in the rocker covers , I'm assuming the 8mm is an inlet the filler cap is a filler cap and what's the other for is that breathing out and is it back to the carb somewhere I have a rover sd1 pic as below

I've shortened the oil filler by removing the extension and want a short version of the breather doofer on the other side so welcome any ideas .. Thanks in advance steve

no,pic,  ? 3 holes, should be 1 oil filler and 1 breather in one rocker cover and 1 breather in the other cover ,,

Giz a chance fella ..  :D

still no pic ::)

Can ya see it now?

yeah  but why are you putting a daewoo matiz engine in a trike :D

oil filler ,as you know  ;) right hand breather with trap ,,left hand rear small breather used to go to vaccume side of carb/inlet manifold  but should have a small ,flame trap, inline in the hose ,, if not and you get a carb backfire they can ingnite the crankcase oil gas and explode  with a bang ,,,normally the only damage they do is to blow the end out of the valley gasket ,,
been there done that  ::) ::)

So I thought a 8mm filter on the little one and 46mm filter on the other if I cut that doofer down would that be ok?

yep if youre thinking of them little breater filter,fancy jobbie,s
they only need  ,flame traps, if they are piped back to the inlet manifold..

I've got aftermarket rocker covers on mine. They came without any holes at all, so we had to TIG weld in the old filler neck. No flame traps, just a breather pipe at the back of each cover feeding into the air cleaner, (I've got a Holley carb on mine).

rovers played with so many differant breather ideas over the years ,, mostly to get an old design of engine upto the latset emmission standards ,,

the two small ones at the back go to the spacers between the carbs and manifold with flame traps in the line.
the bigger front one goes to the air filter.
If you dont have the little ones on the rocker covers remember to blank the holes off (Them little rubber caps are good for the job) on the carb side or you have problems trying to get your mixture correct.

Thanks guys think ill just put fancy filter things on them then , so last question where's the black hole on top of the blue bit that's attached to the right carb go? Very technical me :)

Ok next question I have a radiator in mind to use with the engine it's aluminium and holds 1.6ltrs so part a of this question is is that sufficient to cool? secondly how do I sort the pipework from the gm180 gearbox can it be blanked off ?

The rad depends on size as well as volume.
I know mine is not a gm box, but I have just made a pipe to go in between.

Here is the pipes I wanna get rid off what's the options?

oil cooler pipes ,, i,ve got the same dilema on ,EMILY, wether to run a cooler or not  at the moment i just have the pipes ,looped, back so that i can run it ,

Always run a cooler on an auto box, seperate from the radiator if you can. This is just in case in the event of an integral with radiator type breaks you don't end up with cooling water in the gearbox or trans fluid in the cooling system.
Running a cooler gives you more fluid volume and extends the life of your box.

I've got an oil cooler on my Borg Warner auto box. I was advised it was essential for the life of the box.

I had a BW65 in the Mini when it was on the road for 5 years (And used to take it up the track as often as I could) and I just looped mine and never had a problem.
There is little pressure so some fuel pipe with jubilee clips would do or get someone to make a new pipe using the old ends.

Would a small motorbike one be worth the effort?

BMW 3 series trans oil coolers are very compact and there are plenty about.

put it this way, if you have one and somewhere to fit it, then yes  ;)

Smee again ok radiator moved to rear of vehicle is the rover v8 circulation pump all that is needed or another pump required?? Ta in advance

My oil cooler's mounted in front of the radiator, at the top of the grille shell in my truck. I was told it'd be much better mounted at the bottom because the Rover circulation pump isn't designed for long hose runs, but I didn't have the room to mount the cooler elsewhere. Most I've seen have been mounted low down, in line with the engine take off.

there is little pressure as standard but I recon that as long as the rad is about level with the box longer pipes will not make a diffence, (they have to run passed the engine to get to the front so going the same amount to the rears not going to hurt)
