Bent valves? Read on...
Apparently if you have a broken cam belt and bent valves all you need to do is put a new belt on and rev the t1ts off it to straighten the valves.
From a PistonHeads thread..
From a PistonHeads thread..
Whilst I mention it, I have seen people change the belt, fire it up and rev the tits off it to basically hammer the valve head straight again. It can work but I personally would never try such cowboyery
And you know everything I have seen? I have seen it and seen the car run for a significant time after. It was done by a mechanic I knew years ago, I was sceptical and didn't believe it would work but it did.
Pug 405 1.6 petrol, snapped cam belt, valve clearance was out quite a bit. New belt fitted, started and it missed and tapped a lot. Revved hard for a minute the tapping gradually quietened down and the miss fire disappeared, valve clearance closed back up.
As said, I have seen the heads drop ff valves so would never attempt things, if the head breaks off you're in the st.
Believe me, people who think they know everything rarely do and are far more likely to know less as they shut their eyes to new knowledge.

Might have been a "safe" engine, so if the belt has gone then it won't bend the valves anyway!

Too many posts.. I need a life!!
To be honest chaps I've done it myself years ago on a car I bought with a snapped belt , 205 1.1 petrol , had just touched and ran on maybe 2 and a half cylinders but came good with some hard revving
And in all my years in the trade I've never had fucked seats with bent valves!
That's just tosh !

Un related but many years ago I had a rather Smokey Orion 1600e caused by being thrashed to with in an inch of its life on a daily basis, a mechanic mate diagnosed the smoking due to glassed bores. As I was only 18 paying a fortune for insurance and doing half my wages on petrol a week he offered a cheap fix @ £1.99.
He sent me to the shop opposite the garage to buy a tin of Ajax powder he then mixed it with WD40 to make a paste tipped some down each plug hole then turned the engine over for 5 mins, put the plugs back in a run it up the road no more smoke well for a couple of months anyway.
There are loads of dodgy tricks in the motor trade so quite believe the valve story.

In fairness usually it's the guides that break and more often than not that is what stops any quick fixes

In all fairness those seats are not fucked because of bent valves those seats are fucked because the valve head has snapped off I can trump that by saying it also fucks pistons too but it's only if they snap off!!!

If an RX8 gets a rear end shunt it can fuck up the engine as the exhaust doesn't have any flexy joints. Can crack the rotors/tips.
Really?
If that's the case they really ARE shit.

I really wish you had contacted someone like Haywards after you had had the accident in the first place. You could have had a decent payout from the insurance instead of a dead engine and a scrapped Rex.
Basically because you had to that big impact to the rear of the car which meant you had to replace the exhaust due to the impact of the bike where do you think a good percentage of that impact engergy on the exhaust travelled up to with no real flexi on the exhaust system It all went straight upto the engine.
I had an accident someone went in to the rear of me at a set of lights and Haywards insisted on checking out their freshly rebuilt engine as any shockloading like that can damage the engine tips. Mine was all ok but the insurance company had a bit of a bottom clenching moment when i told them the engine was being inspected for damage with a possible rebuild cost of £2.5k....
such as shame as it sounds like a shockloading problem has occured and damage a seal or tip which has now fragged itself into an engine failure when you took it to 10/10ths.

these cars have nothing going for them do they?! They'd work better if they had a hole in the floor and Fred and wilma in the back

Latest from Pistonheads. A SIX page thread about removing 2 rusty bolts from a Clio exhaust.
Do people just post random bullst without thinking about the job in hand?
Hammering on a socket so near to the catalytic converter?
...Seriously?
If you use a hammer near the cat you may well shatter it internally. They are actually quite brittle inside. Don't use a hammer anywhere near a catalytic converter, OK?

It's very bizarre, the OP states his garage has no power so he can't use a grinder or whatever, cue 15 people telling him to use a grinder, then another 15 people telling him it's too dangerous to use a grinder
My reply to that was "By the way some of you lot are going on, it's not like he's wrestling a live aligator under his car"
Then some bright spark puts a pic of a DeWalt re-chargeable reciprocating saw on there. (Have you seen the size of them?)
I replied, "How the fuck is he going to get that under there with a car less than 2ft off the ground"

Been a while since I posted words of wisdom from Pistonheads. Wow...
What do you think sunshine?
Hi guys,
This will inevitably be a stupid question that will probably have the answer I expected, but I will ask anyway.
I have an E36 328 with some cheap n nasty XS power stainless steel exhaust manifolds. The 3-6 mani has completely cracked and sheared just before where it joins to the downpipe (so when the 3 go into 1) so it is essentially running with the exhaust ending at the end of the mani. Having noise tested it at 105db at part load, and having it apparently louder from the outside, and also as the lambda sensor is in the downpipe and thus no longer getting decent readings, I need a quick way to fix this before I can find the time to get under the car to remove the downpipe bolts so i can get the manifold welded.
I have some short rubber piping from an S13's standard intercooler piping. If I bunged this over and jubilee clipped it on either end so that it covered and connected the two bits, would the rubber likely burn/melt etc? Do i have a temporary quick fix option that doesnt involve removing the bottom bit of the manifold?

I cant go on that forum any more, had a 3 day barnie with the men who developed the focus rs. there were saying that its impossible to get any more power than 265hp out of them, when I replied with 10 dyno graphs of engines over 400hp they banded together to say I was a lier and must be making it up cos they made the focus rs, and even the guy I was sticking up for mugged me off the f¥£ker. boiled my piss

now im getting all angry again thanks mate,
why is that forum so full of experts, think every vehicle development team ever that has walked all must be on that forum, its a shame as there is some good things on there.
