Situation with GF's Punto

I didnt bother getting the head skimmed - Faced it up myself with WD40 and very fine wet and dry + stanley blade. Came up like a mirror. Can also see the stick I used to cut the valve back in with. I would officially hate to do all the valves in a 16v head. Nightmare!

It has already survived a trip to birmingham for a night out on saturday and a trip to shrewsbury yesterday. Also changed Oil, leads, plubs, filters, cambelt, coolant, head gasket and head bolts. (obviously the valve too)

Only problem I had was my own fault. I mixed the shims up when putting them back in so it tapped like hell at first. Had to used feeler gauages to find out the distances and swap them round. Got it right second time round - silent engine now.
 
nice work. they're a good engine to work on them are them.

i would've skimmed it as well though, for what it costs it's worth doing.

Time was against me though since the car had to be OTR within 48 hours of going wrong since the gf has a 50 mile daily commute. My cousin who is a trained Fiat mechanic also said that Fiat never used to get them skimmed when taking the head off which gave me some confidence :) It came up like new with no marks at all, all the gulleys were clear.
 
maybe so.. but i still would've lol.

i have that engine in my cinquecento albeit in a different state of tune, and wouldn't like even the slightlest chance that the head wasn't flat!

Any easy ways to increase bhp? It goes quite well now for the size of it :)
 
i know of a bloke who can sleeve the TB and take it from 38mm to 43mm. That helps. Then theres just the usual, induction, exhaust, headwork etc.

Mine has been skimmed to increase the CR, lightened flywheel, 421 stainless straight through exhaust, cda induction, all tweaked with a megasquirt standalone ECU.

a lot of gum in there. how many miles on it? looks like the oil changes arnt frequent enough (..... good old long life servicing)
 
As said, I would have skimmed it anyway.

Do look out for oil leaking out of the rocker cover at the corners in the seal where the camshaft goes in. They sometimes need a bit of something to seal that area.

Already sealed it their mate with sealer, there was sealer already their so thought it was best :)

I think a Fait trained mechanic can be trusted on the head not being skimmed tbh.
 
oh christ lol no chance some of the gum caused a valve to stick? recon it was plain straight forward heat that killed the valve?

i recently helped a mate buy a 20vt mk4 golf (thats what she wanted), inside the oil filler there was gum in there etc. turned out that it was having oil changes once a year, the oil was staying in for 12k miles ish. sad, if you ask me.

170k golf doesnt have a trace of gum, tappets are OE items and still silent :D
 
i tune these engines, and work with others that do. and when you do things like double the power output of them.. you learn a thing or two, and one of them things is that an alloy head will warp slightly when you torque it down.. and it should really be skimmed, or least professionally checked before refitting it.

Indeed.

The local FIAT D.E.T. and A.T.A. Master Tech. says always Skim it.

That's more than 20 years of FIAT experience talking there.
