172 Cylinder Head blown!!! crap!!!

[BigBarry172]

Car started making a horrible noise last night & lost most of power.

RAC man came out & says that one of the spark plugs had blown off & wrecked the threads of the cylinder head. Can't screw a new plug in.

He advised me to get it heli-coiled, or I will need a new cylinder head (expensive! £1000+ ???)

Any thought or idea's on how I can keep costs down & can you recommend any good garages / parts places to go to? Any suggestions will be welcome please! (within reason!)

any competant engineering company should be able to helicoil it for you, at minimal cost.

Get your yellow pages out.

Mine did this... looks into mystic ball.... Was it cylinder 3 per chance?

 

[Fred@BTM]

thats quite common

The same thing happened to a friend of mine years ago, he had a VW Camper. Darn thing popped out as he was going up a hill, he was none to chuffed, he bodged it with plumbers tape to get him home. He didn't get it permanently fixed, went out and bought a Honda instead. lol

isnt it?? always thought the car was most likely to blow the plug at hi revs.

Mr Darthcake you are a genius!!!!! it WAS cylinder number 3!!!!!!!!!!! spooky $hit!

Any advice on the best spark plugs to replace with? Or are they all pretty much the same?!?!!

 

[Russ.]

all pretty much the same, some last longer than other but in terms of performance any of the major brands ngk, champion etc will be fine

 

[MATT BLACK]

Easy job - put your legs up and stop worrying

 

[paddymph]

whats the cause of this then? never heard of this??

some may have multiple contacts which promise better performance, in my experience tho its best to keep it simple. i tried a set which had 4 contacts on each and they ended up being changed out by an AA bloke for some single-contact ngk ones! i tend to stick to champion

NGK PFR6E only £25 each from ren or £9 from your local factors

what actually causes this though?

what actually causes this though?

The spark plug comes loose then when its on the limit it blows out and damages the threads. One theory was its down to plugs not being fitted and torque properly.

ive seen it on cyl 3 also....

 

[PinkCat]

That sounds pants.

Is it a common thing in 172's? i cant afford that much money if mine blows!
Is it actually to do with drivin the car at hi revs? i gonna have to start drivin like a granny now!

It happens when running at high rpm for a long time its not that common though athough it can happens.

why do people always say gonna drive like a granny or a woman? i normally go out in my car see some care flying past or zooming up the dual carraige way i go yea i'll av em as i go past i notice there's a girl inside and she's stuck behind a middle aged guy?
