what am i best to do

[-Dan-]

Hey everyone, my spark plug on cylinder 4 has stripped its thread on my 172 cup, ive got a company down the road that makes race engines and is willing to timesert it for me

ive got to get the cylinder head to them, once i get the head off how do i stop the cams moving while there at the engine shop so they go back on in the same place, im going to replace the dephaser pullet while its all off aswell as the belt to be safe

ive read its not best to do this yourself but ive done a few dohc cambelts before but never a clio sport! ive not got much choice but to it myself, i need the car back up and running by next weekend so im going to working my a*se off every evening freezing my t*ts off, ive also decided im taking the engine out to do the belt on the bench etc more space to work

Thanks Dan

Do the timesert yourself or get the car to them. Did it on my old Clio at my parents house.

Much much easier / cheaper than stripping the whole head off.

Happened to mine on Cylinder 1 - http://www.cliosport.net/forum/showthread.php?719039-Trophys-Went-Bang-(Gutted)

The TimeSert is the only route i would go down after watching videos and reading about it.

Timesert, is that like Helicoil?

Similar I think, but better somehow....

How do i stop bits of metal from tapping falling into the cylinder? i will deffo go timesert route, seen to many helicoils pop out

Im not sure how my garage done it but they did say there is a tool or kit that can be used to collect any shavings or dirt.

so your head never came off? if theres a way i can do that save me changing all the gaskets, belts and stuff would make my life much easier

 

[TheEvilGiraffe]

Vacuum cleaner and a small tube. The rest will blow out. There's not gonna be huge chunks of metal in there !

My head never came off, There was no damage (i was lucky)

It cost me more in parts than anything else as i bought new plugs & HT Leads.

The garage also had to buy the correct timesert kit as they never had one for the size i needed and that cost about £20.00

ahh okay then, i will have to look into getting a timesert myself, ive never done one but have done plenty of heli-coils, well say there shouldnt be much metal in there but somewhere there part of spark plug hopfully it spat it out when it snapped, i know they shouldnt be Bosch but i didnt put them in

Buy OE

OE HT Leads - 8200334440 £53.54+vat

OE Spark Plugs - 8200239321 £12.54+vat Each

As said with mine it was caused due to an injector jamming open but make sure that the spark plugs are at the correct torque setting

LOL at that plug! eBay is usually chepest for oem NGK plugs IME

tell me about it, wondered why the car was running abit strange last week, just typical the thread stripped nice 5 min job has ended in a nightmare for me, track day next weekend and dont want to lose my £230

It cost me around £100 to have mine done with full compression test and everything else.
