To start the story from the beginning:
I decided to change my cambelt around november time. Happy motoring for a month or so, then when i drove to work to pick up some tools to fix my range rover some batty woman stepped out in-front of me and i had to do an emergency stop and stalled the engine. When i restarted it, it sounded a little noisey and not so much poke so i limped her to work which wasnt far as i was at the front gates.
I took off the top cover and found the cambelt had jumped 2 teeth and after much shouting and swearing and doubting my ability to tighten a cambelt correctly i found a small plastic looking thing with pully marks on it floating around in the casing. I can only assume that that plastic got caught underneth and caused the belt to jump. Or perhaps the force of the stall made it jump a tooth but i am 98% sure the belt was tensioned correctly.
I re set the timing and thought "it will either go or it wont" thinking that if it bent a valve i wont have compression and it wont start. To my amazement it started straight up with the old belt on! So i rushed down to the local stealers and put a new LR cambelt on and put everything back together. Took her for a test drive around town and everything seemed fine. Lovely jubbley...just in time to take it home on friday.
As soon as i got out the town i realsed it wasnt quite as strong pulling as it used to be and to the trained ear i could hear a slight tapping sound.
By this point it was the weekend before christmas and i didnt fancy an engine strip down just yet. Perhaps if i borrowed mothers car whilst she isnt at work and try and find the tapping sound after christmas....
You can guess whats comming..
One morning i am at work and i get the phone call. She has popped out and the engine has stopped. I tow back to work and a little digging about doesnt seem too good.
Remove the bearing carrier on the cam shaft and found 2 of the cam followers were missing there tops on cylinder 2 and 4. Others cracked but not missing any pieces. But where were the pieces?
I removed the head and found them! Pebble dashed across the top of my pistons. In cylinder 4 the cam lobe had spun around and flicked/smashed the collet from out the valve and it dropped.
Whoops!
Sorry its been so long winded...kinda got carried away but heres the pictures:
Cam follower:
Spot the odd one out:
Up close:
Piston:
On a compleatly unrelated note. Does anyone know of a freelander L series engine going cheap?:biggrin1:
