push rods won't fit
Turbo Mini Forums

Put my vmax head on today,but the pushrods wouldn't go through the head where the holes have been sleeved.
I skimmed 4 down with the angle grinder and put a chamfer on them.
Just wondered what other peaple do ??

dont know the answer to your question mate but ring vmax in the morning and ask them what theyd reccommend

no longer a series, but still 1.3 turbo.

i drill them through so the rod just sneaks by

Heads all torqued down so don't really want to take it off again,the ball end on the rods are approx 1mm to big for the holes.

If I redrill them there is a risk of breaking through into the inlet ports

Think I will take some pushrods into work and regrind them properly.

Ball end?

Top or bottom?

assume he means bottom

Heads torqued down?

4 of the head bolts go through the rocker posts?

Surely getting the job right is worth a new head gasket. It sounds like it is the bottom ball/cam follower end. Not the place you want to butcher as it is a very stressed part of the engine.

To be honest what sort of performance head supplier sends out a head that needs further modifying?

JF.

my thoughts are the same as johns

but i did not like saying anything bri

there will be enough meat in the sleves to bore these out

if its a boarder line case fire the head back to Mr V. maX!!

i would not ne happy

Update..Phoned vmax,he said grind the rods down as they normally have a radius on the outside so won't affect contact area.
Apparantly racers grind both ends of the rods to lighten them.
He said don't redrill the holes as It would prob break through to the inlets as they are massive.

It's a grp a "monster head" 37/32 by the way

Is this for a turbo application Brian?

with that size sleve bri

make sure the push rod angle on lift and fall is not going to catch on the side of the seleve

my opinion is that it will

this would place a bend in the push rod

eventualy wrecking the whole valve train very quickley !

please check

37/32!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Good luck on that not cracking between the valves if its a turbo.....

how did you get on with this... my head is arriving very soon and will have sleeves

ALL 940 heads have got sleeves. I just cannot understand why allegedly professional head modifiers market their heads with them having sleeves. Fuck, Rover fitted sleeves. What's this to brag about.

In this case it seems as the original sleeves have been discarded and OS ones fitted. Why, I cannot understand, but I guess the manufacturer should be able to answer this???

speak with stuart again, I know he will do what he can to sort it out

I had my engine built buy him, a couple of problems arised but he did all he could to sort things out

I don't mind using them ground down,after all the outer edge of the sperical has no contact with the cam follower
