yeah i'll get to the motor in the next few weeks and find out what it is..

filter was a new ryco.... still had to pull the motor out Ando.. had a knock but not deep enough to be big end.. i replaced all the lifters and still the same thing.. I dropped the sump and pulled the oil pump and when i put the drive in and turned it i got to one point and it seemed to get stiff to move then come clean after that so i'm hopping its that.

ok so on more of a look the Oring on the oil filter was cracked and where it was facing was right at the dissy.. but the funny thing was that where the dissy over hangs the block the oil was hitting that and making it look like it was coming out of the dissy hole.. all good everyone thanks for the input.. 

Yes.

Hi guys just wanted to know if anyone els has had this problem or know what it might be... I have just started u a new race engine and I have oil pissing out the dissy hole... I pulled the dissy out and it had no Oring but this dissy was in another car and didn't have a problem.. the oil pump was also in another car and never had this problem... any thoughts would be great.. I'm meant to be racing on saturday.. lol

its a Sure cam just to let every one know.. and the SC stands for Sure Cams... the OH stands for Over Head 28Z is the cam grind and the -8 stands for the lob sep.. 

Ok I have a cam that I'm not sure on whi made it.. on the back it's stamped SC OH28Z-8 if anyone could help that would be great..

well i guess i will be calling them in the morning.. thanks guys

as some of you said it didn't work... I was told it would but.. so for now I have moved on to my 60thou over bottom end with 250 rods and ARP rod bolts. 

Ok I need to know some of the machine shops that people have been using and do good work?? I'm thinking of P.E.A.C.H performance..

LOL stupid QLDer's can't drive

Hay now now.. lol 

it was made for a speedway car.. 

sorry had a brain fart.. its 107.5 lobe sep..

Oh and just to let everyone know that the cam numbers stamped on the back " CM250S " stands for " CM250 " is to suit a 250 xflow and the " S " stands for a unfinished cam so its just a blank cam that other cam makers buy like wade cams or sure cams or cam tech.. 

ok so after look at it and thinking about i redone the cam.. and this is what i got.

lift Ex 574

lift In 498

Duration @50 Ex 280

In 280

cam centerline Ex 250 after TDC or 70 before TDC

In 105 after TDC or 75 before BDC

but I can't work out the Lobe sep.. can anyone help with that?

I think I will just get a sure cam.. I have had his cams before and they are great.. 

its a dynotech cam cm250 I thort was a 214 214@50 495lift

 

I have a few in the shed ill take a look tomorrow at the spec sheet and part number

so would the S at the end mean a solid cam?

well after using my diel gauges I have the cam at 

lift Ex 501'

lift In 496

Duration @50 Ex 226

Duration @50 In 249

and Lobe sep 114.. 

I can't see that being right tho..

Ok just just wanted to ask if anyone knows this cam maker.. on the back of the cam its stamped.. CM250*S and also has WRC.. any thoughts..

ok so after many phone call and visits to many stores I can not find anything that will work as its already one size bigger.... my only option was to go to a 1/2 hole and then it becomes to close to the water jacket and cylinder... so what I have done is tried this stuff called pro weld.. its a 2part glue/weld.. they reckon its a chemical weld.. but we will see.. i'll bolt the head down this weekend and see what happens..

one thing to mention is the motor is not a bad combo..

cam is custom ground to suit me rev range. 2800 - 6500

soild cam and lifters

double row timing chain

harden push rods

adj rolla rocker

351 valves

head has been ported also has been decked 30thou

40thou over piston and 200 rods

blanced 

5.5KG flywheel

power bond blancer 

custom made extractors 3" exhaust

36lb injectors

adj fuel reg

not really sure what kinda power it will make i was hoping for around 230hp.. this is going into a speedway car. 

sorry i didn't get the size of the hole 2day was pretty busy and now i'm busy drinking beer.. up QLD.. what a win.. anyway.. I have a 60thou over motor swell but the piston have a good size dish to them and also the piston is far from the deck hight.... so I was thinking of running a set of FG xrt6 rods.. I know they are taller than the 250 and shorter than the 200 and I could always machine down the top of the piston.. has anyone ever played around with putting AU to FG rods in xflow's and if so can you tell me the in's and out's?? my 40thou over motor has bugger all dish and has 200 rods. would like to use it but if I can get the right rods for the 60 over motor I think i would be better doing that.?

i will measure it 2moro and no its not broken off in the hole

its the same hole that the first dowl goes in..
