If it is the oil filling up in the heads after shutting the motor down the oil should have drained back to the sump and oil pressure should be back to normal once you start the motor again.. Did this happen.

If it is still noisey with no oil pressure you have snapped a oil pump drive shaft or did not fit a welsh plug properly and no oil is getting to the heads.

I dont know if the windsor and clevo are similar in design but I run a milling high pressure oil pump in my windsor and run high revs for whole stages of winch challenges without any problems.

Jut had a look at my motor that came out my MQ, it ha a normal front pickup. The chev i cloe to the diff in my GQ, eem the MQ i better fit a V8 to

hey mate the windsor and clevo ford engines were entirely different. the oil galleys in the windsor are better constructed which eliminated the clevos problems. but reverting it back to std will solve them. its got something to do with the ammount it can pump through, all ends up in ur top end and fries the bottom end. a restrictor will work but its really only a bandaid style fix imo.

Another thing that wrecks distributors and cam gears ect is that there is an early an late clevo block, you must have the correct distributor shaft, one is just over and one just under 1/2 inch, if you have the small shaft in the large hole block then you will have issues with distributor gear, cam gear and oil pump drive.

hey guys i pulled the engine down during the week & no suprise the main bearings are all gold again with no case hardning left , im getting the crank machined with new bearings , getting rid of the high volume pump & getting a high pressure pump set up for it & hopefully it should be ok then,, cross my fingers , thanks alot for your help.. jess

A high pressure pump?? Oil pressure shouldn't exceed 80 psi or you are still looking at brocken bits.

thanks mate, ill find out more about that before i do it.. only prob is everyone i ask tells me something different

high pressure pump? i have heard of a high volume pump: "a pump canonly create flow it is restriction that creates pressure" just had to clear that up. what sort of clearances are you running? is your crank running in oil and creating windage? ie airating the oil causing an airlock? for christs sake the idea of replace it with a chev is no better these are all just air pumps and all have their pros and cons. having seen clevlands successfuly run wet sumped in road racing cars i think that i would be looking at your oiling system. check....pickup hight from sump....pickup for leaks...sump design...windage will also hinder oil return to the sump from the top of the motor more than excess oil at high revs...its a cause and effect thing are you adressing the symptom or the problem? sorry bout the rant and the spelling i just hate to see people chasing their tail!!!

hey mate thanks 4 da info sorry i neva got back 2 u,, i think i am chasing my tail with this, i put in a stock 351 from a wrecker last wednesday it was quite as & by sunday already has a slight bearing noise & now getting louder with no offroad use, now im thinking instead of spending more thousands geting a cleveland built i mite scrap da ford idea & go chev.. ive had 2 many dramas 2 take da chance,,, thanks mate

if it happens that easily, you clearly have an oiling issue....probably pick-up related.
a stock clevo will not suddenly just get noisy like that without angles causing oiling issues.........these motors have been around forever and run forever.

double check your oil pick-up system over and over till you find the issue.
Its not just a Ford thing.

From memory, the windors need to be installed on a slight angle, to one side or the other, i cant remember which one.

Does anyone know what the angle is and to which side.

i agree with hotrod, sounds like there is an underlying problem. Have you used the same pickup and sump for all of the engines that have failed ?

hey gq351, ill take on of ur clevos if ur donating it back to earth they are fantastic engines and i have stripped a heap of them! want to run one im my gq, and as far as windsor angling goes, as far as i know the only angle used is they dip backwards slightly at the bell housing but they shouldnt be tipped to any side, that would just be silly engineering

Knew i saw it somewhere, not sure what the go with the 3 degrees is though.

I just Done the conversion myself I've got a heavilly worked 351 cleveland in my maverick with no oil pressure problems. I have driven it for three days solid no prob's as yet. I used a bronco reverse sump with a mellings high volume pump. I have a speco oil pressure guage which sits on about 85 when it starts and drops to about 60 when the engine is hot. My clevo is a hard reving motor and has never lost pressure. Two things that you might want to check : 1 make sure there isn't a hair line fracturwe in your pick up pipe I've seen this before especially around the brace that runs to your engine main caps if you are using the bronco sump . 2 make sure that there is a gap between the bottom of your pickup and the sump sometimes if you are running a heavy weight oil there might not be enough gap or if the pickup unknowingly got bent.
dont give up on the clevo you would be silly you will find that it is something simple. good luck

hey guys thanks 4 da quick advice, no mucking around here.. this is da 5th engine now all with different oil pumps, i have tried standard,high volume,high pressure ect, i have also tried da standard falcon front pick up sump.. oil pressure is still around 55-70psi, but just very noisy, so instead of spending 5 grand or so on another cleveland & risking da lot, i was thinking of maybe going a 454 bb chev 4 for around da same amount of cash. theres alot of ideas floating around,, thanks again guys cheers
