ones a 1.6 and ones a 1.7. its not rocket science to work out that the different bores mean the head wont match up.

OldDan

Could be stroke

steve18

ok thanks guys. what i was wondering as well my big end had a slight knock do you think i could get away with changing the shell bearings alone. or will i need the crank to be reground.

if your going to do it do it right!! its like saying reuse the oil once you have rebuilt it lol

OldDan

I'd buy another bottom end. Cheap enough.

its a combination of bore and stroke on the 1.7s.

Other than a new bottom end he could fit the later 1.6 engine with twin VVT if its more power he wants! although hed need to play with the wiring too!

So many issues really. I was talking to my mechanic the other day about dropping the puma 1.7 in the fiesta, thinking it's not too much of a challenge lucky for me my mechanic is quite possibly the best in the uk. Massive job. If you want to do it you need a donor car. Gearbox change, ecu so much crap needs to be done. I genuinely thought it would be a case of swap the engine out and job done. Lol what a fool I was.

Ps he is that good: sent my friend to get a tyre changed and as he drove into the garage he told my mate his rear axle was bent. The engine was still running and he hadn't even got out of the car. He got a ruler out to show him. 1 cm wrong and he spotted it in sub 10sec.

On the subject of bottom end for a Zetec s mine is solid and might be for sale soon. Long story short went to another mechanic while mine was on holiday for some head work. He timed it wrong and broke all the exhaust valves. Head is ruined and will never pressurise as the valve ports were all smashed and broken around the edges. Off the road for at least another two weeks and if he can't get a head it will be a new engine.

It's possibly one of the easier engine conversion you can do!!... Can be done in an afternoon if you know what your doing

spotting a 10mm change in axle width via a ruler at first sight? fuck off lol
worn bushes would do that!

best in the UK....

why would you take your car to another machanic (that fucked your head) while "your" mechanic is the best in the UK?

PumaJay

i think this "best mechanic in the uk" might not be all he appears to be!!

Only a few water and oil ways need changing/blocking but for all intensive perpous its a total waste of time and money.

Its as simple as a engine change, all you need to change is the block inlet manifold altornantor drivers side engine bracket engine bay loom and ecu and change a few pins on the ecu end of the loom, Any fool with a spanner can do it.

Bull that cand be a number of things.

Sorry but no Zetec-SE engine is solid there all weak as shit, Well if it did that much damage just to the head what did it do to the pistons and bores? :\
