So that head has run on that block?
Much oddness. I may have to break a family member's car at this rate! Is that engine related to the ALT at all here ?
Yes, that crossflow 8v head does run on that block. The 20v head fits perfectly too, but would require a crank timing belt pulley change and piston mods to run.
Do not break the family members cars as that is a 1.4 or 1.6 16v IIRC, which is based on the wee block. Completely different.
This engine in my pics above is an 06X type block. Internal waterpump and no intermediate shaft. Light, very light.
Possibly it is related to the ALT block, but that would have a bigger bore being a 2.0, and I am not sure if the ALT is a tall block either.
I thought you said that block was from a certain hum drum piece of VW mediocrity, aka Golf 4, 1.6.
So there were two 1.6 16v engines?
Is yours a 220mm block?
There are two types of 1.6 engine fitted to the mk4 golf that I know of (possibly more). One is a 16v based on the wee block, and another is the 8v crossflow based on the 06X block.
My alloy block is a short block as it has the same crank to head face dimensions as a 1.8 PB or 2.0 9A for example.
8v crossflow in 1.6 capacity. A whole new topic just opened up...
'least you know now why I thought it was a small block!
holy feck this is confusing, i have read it twice now, and i think im there now
mk4 golf 1.6 16v is an alloy block based / similar to earlier small blocks
mk4 golf 1.6 8v is an alloy block based / similar to earlier big 827 blocks, so does that mean larger cranks will fit?
Next question is which blocks were sold in which cars by year or chassis.
Second question is whether anyone would like to buy a Golf 4 1.6S, which I'll pinch off a relative, minus engine
Confusing? No, it is all in the mind, my mind anyway.
I reckon a 1.8 crank would fit in the block fine, not sure about 2.0 ones though. the 1.8 swap would be a doddle using oem parts too.`
Need to be long nose cranks for chain driven oil pumps. Unless going to dry sump of course.
Got to have the crank out of mine to remove the trigger wheel anyway, as the short stroke will spin fast.
They are fitted to mk4 golfs, you will not have to wait long for one to turn up in the scrap yard. Modern cars are pish, but do make excellent donors for the older generation.
which older engines used chain driven cranks??
None - they're similar to the internal water pump 1.8T.
~ ?2001 onwards?
None, you would need to use the crank out of an 06X type engine like the later 20v petrol engines.
The older IM shaft blocks like PB and 9A use the short nose crank.
Edit, Good to see you have got a grasp on this now Mr Eyre.
holy **** so you would have to butcher a 20v for a longer stroke, sounds ideal!! less 20v's and lighter and faster 8v's brilliant!
I have been dismantling the multivalvers for this very purpose for a while now Alan.
It does not need to be a 20v engine you break though. Any 06X type engine with a suitable crank will suffice.
Cough, Beetle engine cough.
This crazy thread came about as the result of a trihijack!
Not sure it was ever meant to be the first alloy block ever sort of thing.
Anyway by the time you have lapped in your 32 valves cerips, the 8v will be long gone.
The thread came about because I was possibly, maybe, I'm not entirely sure.. being a smart @rse and thought I'd trumped the Danster on the identity of the lightest 8v block, being the barely-heard-of 1296cc version!
As it turned out, it was the 1.6 crossflow alloy block sat up his sleeve until this very post!
The short or long nosed crank effrontery!
Read, weep, and note the cog
that block looks similar to the one in my dads mk1 octavia. 1.6 8v crossflow, 104bhp. his is on a 53 plate so one of the last ones before they launched the mk2 octy.
