(T) Fixing My 1.4 Bravo Engine Misfire

And more pitting on the head near cylinder 1. Is this minor pitting normal?

cam wear is minimal, and with a good clean up and new set of valve oil seals you'll have a good head. that pitting is normal. a head gasket will seal it fine.

shame the bottom end isnt worthy of it. if you're thinking long term then a scrapyard engine is best bet, but since your head is so good just get the bottom end, allowing you to inspect it with head removed before you buy, ensuring you'll get a good un.

Cheers jug.
Ill have to have a think Im doing all this on the street and I don’t have a engine hoist.

A bad bottom end was my worst fear. I suppose I could get a scrap yard block delivered build it up then hire a engine hoist to fit it.

What’s confusing me more than anything is piston 2 was always the one to oil up yet it looks the best and has the best compression, where as 1 has the worst compression and worst scoring.

Ill spend the rest of tonight cleaning my parts and have a think.

oil in cyl2 probably due to leak in valve seal, and low compression on cyl1 due to piston ring leak. oil problem will be sorted with your head work, but compression on cyl1 wont improve. you could run it with low compression on cylinder 1, it isnt the end of the world, and tbh 153psi is plenty for good running. look at it this way, it wont run any worse than it did before the oil problem. how long until the ring fails? who knows, but i wouldn't expect it to happen too soon. maybe you should stick the head on and then sell it in the not too distant future

Im thinking of getting a scrapyard block to my house.
Putting my good head on that in the shed.
Then getting a local garage to take my car and engine, pop it in.

Then get them to deliver the car back to me, and ill finish it off.

I cleaned all my valves today, the exhaust valves where hard to do.
Every inlet valve had thick carbon on the back.

Infact there was only one valve that was clean cyl-3 exhaust valve was light brown on both sides.

All clean now anyway

pics?

Ill get a pic of the clean valves this afternoon, they are all in bags in order dont want to mix them up.

For now a pic of the almost clean head.

Im a little unimpressed with this picture, all the muck has been removed but look a bit crap in the pics.


Im thinking scrapyard bottom end.

valves good as new now.

bottom end wont cost much. ring around to see.

Nice one jug im ringing round first thing tomorrow for a bottom end. If i can put it together I should have a engine ready for a lot of miles.

Do you recommend getting new piston rings and big end shells?

Block will be bright red rocker cover black with silver letters Dip stick tube is now black

While ive been thinking painted my rocker cover with some old exhaust paint we had, should be good to 500deg.
I did silver first very thin, then masked and painted the black. black is a bit too matt but its what i had in the shed, looks better than oxidisation.



Oh if anyones got ideas on finding a good bottom end, I need inspiration. Only found 2 scrap yards local and they wont split the engine. Spoken to a few engine reconditioners but the couldnt help.

just buy the whole engine, or buy a bigger engine?

your cinq has a better engine than mine 20 more bhp's and it looks smaller like it might be lighter

without rubbing it in much... it is a much better engine.. better on fuel and more powerful than the 12v...

didnt someone say the 1.6 / 1.8 is an easy swap? if not, if the 1242 16v goes in easily, then so will a 1368cc 16v
