Ian Kinder (Bagpuss) - Joint Peak District AO Posted August 7, 2015 Share Posted August 7, 2015 @Stu, phew....................... I didn't think Honda's broke @ Chris, most google results I've seen suggest it to be an non interference engine! Quote Link to comment Share on other sites More sharing options...
Kingster Posted August 7, 2015 Author Share Posted August 7, 2015 fingers, crossed. How many rev's approx was it at when it broke? about 4k i'd say Quote Link to comment Share on other sites More sharing options...

Dave Eastwood (Gadgetman) - Club Chairman Posted August 7, 2015 Share Posted August 7, 2015 I thought the Pinto was the last Ford non interference engine in Westfield circles? Quote Link to comment Share on other sites More sharing options...
Dave Eastwood (Gadgetman) - Club Chairman Posted August 7, 2015 Share Posted August 7, 2015 I see what you mean with Google - seems to suggest they've got extra deep valve pockets to accommodate valves at full extension. have you tried turning it over by hand and feeling for clashes?

Kingster Posted August 7, 2015 Author Share Posted August 7, 2015 Not yet Dave, will be investigating tomorrow. Probably put a borescope down the plug 'oles. 1 Quote Link to comment Share on other sites More sharing options...
jonjh1964 Posted August 7, 2015 Share Posted August 7, 2015 As I understand it European Zetecs are interference, U.S. are non-interference - therefore be careful buying cams etc from the the U.S. Quote Link to comment Share on other sites More sharing options...
GuitarmanUK Posted August 7, 2015 Share Posted August 7, 2015 Sorry to here this, not good. The Zetec in my Zero was a new crate engine and I have done 8500 mile in 3 years in it. However, as the engine was originally built in 2004 ( or so we think) I have just had the belt changed, for peace of minds sake! 1 Quote Link to comment Share on other sites More sharing options...
Lyonspride Posted August 7, 2015 Share Posted August 7, 2015 Yep - just back in, AA man was uber quick luckily as I'd left the house unlocked while popping round the corner for a quick shakedown run. Only myself to blame - I looked at the cambelt in my hand (after changing oil pump) and though "hmm, maybe I should put a new one on while I am on". But didn't - cos I are mostly a muppet. Famous last words! Might not have done much good if you'd put on a new belt, as it's usually the water pump, tensioner or pulleys that fail and take out the belt.

Ah I see. Will find out more tomorrow. Learning all the time Quote Link to comment Share on other sites More sharing options...
Kingster Posted August 8, 2015 Author Share Posted August 8, 2015 Well, I can now categorically confirm that the 2.0 silvertop zetec is indeed an interference engine - as there's plenty of evidence looking down the bores with a scope. Decision time: 1. Remove head and fix/swap 2. Shove another Silvertop in 3. Put in the ST170 engine that is lying in the garage. While option 3 appeals, I was planning on fitting this engine later along with a few other upgrades etc. so not sure if it is ideal at this moment in time - plus I have just had the silvertop mapped, so that time and money would be wasted.

Dommo Posted August 8, 2015 Share Posted August 8, 2015 If option 3 is taking you off for road for the few days of British summer option 2 is the best bet. With your best man maths, the spare engine should have a cambelt already on it which would offset the cost of the engine Quote Link to comment Share on other sites More sharing options...
Kit Car Electronics Posted August 8, 2015 Share Posted August 8, 2015 2 (if your current engine was standard) Quote Link to comment Share on other sites More sharing options...
Kingster Posted August 8, 2015 Author Share Posted August 8, 2015 Yep std engine - so 2 is defo the best bet - time to find one I guess. Here's my old cambelt - ouch! Quote Link to comment Share on other sites More sharing options...
