Willy manifold, quick question!!!

[simonr85]

When i took the willy manifold off and looked down the end where the 1 pipe goes into 4, there is lots of weld all round the edges and in the middle, now my mate says if i smooth all the weld off i will notice an improvement is this correct? i cant really see something like that making a difference but anyway he has took it to BAE to get it all smoothed and is going to polish the outside while its there :lol:

sounds cool! unless the welds were really proud and causing an obvious restriction i doubt you will notice anything, but it cant hurt if its free! haha

[simonr85]

well this isnt the best pic i could draw but the red bits indicate how messy the welds are around where it splits to 4 pipes

you may feel some difference if they are that messy, however, if the muppet who did them in the first place did it that bad, i wouldnt put much faith in the ability of them to hold and seal once they are ground back! lol

it is a common fault for the manifolds to crack there and blow - hence the weld. I would try and find a better original than grind away weld that would weaken and brake.

[simonr85]

well they are not that messy but i drew it freehand so was hard lol

are the welds not there from when the manifold was originally made?

[northy]

i dont think so no. It would of been cast originally as one piece. Should be nice and neat as standard.

Grinding the welds will weaken them

[drsmith1979]

no, as northy has said, its a common problem to crack there so people get them welded, obviously some better than others! lol

[simonr85]

cheers guys

get it welded around the outside if it goes as that won,t affect the performance

It's tubular, not cast.


Mat.

i know mat i ment the splitter inside is cast then fitted to the tubular steel down pipe if u get my meanin.

u dont know wtf u on about lol

the 4 pipes..of the tubular mani are welded at the bottom where they join

this is a weak spot as u can imagine how hot things get just there, the 4 pipes merging, heat collecting there etc.

simple case of grinding down the old weld til u get to the good metal of the pipe, then re welding . can be fettled with a grinder/dremel to get a nice clean finish

no reason why a rewelded one would be any less effective than a new un.
