Were's the best place to get them!??
Its only for a engine im playing with (diy expermenting) so has to be cheepish rearly!!!
Or is there any standard common'ish engines that have removable ones that i can go on the robb!!!

Cheers in advance!

 

if you mean that sqirt the piston then some of the zetec engines had them in mate

 

what engine?

ford silvertop (upto 1996) 1.8/2.0l zetec ones are about Ł4 each from ford

 

well there for a 1341 8v g60 engine im playing with!
Read a build thread were a bloke fitted them into a redtop and i always thought if your gonna do lots of mechining then why not fit some if there cheepish to buy?

 

Anything that helps keep the pistons cooler is a good thing right?

 

as long as they dont drop oil pressure to low at idle,

 

hmm dint think of that!
is there anyway of working it out or is it just give it a go and see???
Dont think they would be to hard to remove if it did, or possably up the oil pressure slightly? Buy using a different pump or modding the standard pump? (i now most work on a spring dont they?)
What sort of problems can you get from to high oil pressure?
Mine will have a lot larger oil sump and hopfully some sort of gated plate so the oil in the sump and the pickup not being able to draw any oil wont be a problem?

 

If you mean a redtop vauxhall lump it was probably me with the ones for my nova:



They have a spring loaded ball in them that shuts them off if oil pressure drops, so no worries there.

They are from an isuzu 1.7 TD engine, if you call autovaux and tell them you want some like in the Total Vauxhall article, they will know what one you mean, about 30 quid a set.

 

not if you get the ones with spring and ball bearing that only open at high pressure

 

Chip, i dont suppose you have any more pictures? particularly one of the spray jets themselves. Just want to know how they fit (screw/press) into the block.

I read through your thread but didnt see any more photos

Your drift them in, you need to be careful not to damage them, its important to drill or ream the whole to the correct size.

We found they worked best at 5.85mm IIRC

 

Great stuff, thanks

edited to say : there are some right spaz's replying on that thread chipper, especially the later pages

 

Fantastic chip!! Yes mate it must have been your thread, ive read so many over the years i forgot it was yours!
Dont supose you have the part number for them as i work for a parts place so should be able to source them though work!
why out of intrest did you chose those ones???

 

I dont know the part number off hand but im sure I can find it out for you.

I used them because they are tried and tested and readily available, and when I ran the idea past Stu @ MSD years ago when I first did it in about 2005 or so, he said that he also had used them with good success on things like RS turbos, so that seemed like a good endoresement.

We use them in quite a few engines in the vauxhall world now, Rob's astra also has them for example and thats certainly taking a massive beating for a home made effort!

 

Sounds good enough for me then!
If you could find the part numbers mate it would be a great help!
