I can remember the good old days of push rods and rockers, usually substantial enough. Some of these pressed steel followers dont look up to the job. Or i am turning into one of those old guys!
If you did another one would you drop the engine on the floor Peter. Are those engine renowned for not damaging the valves when in contact with the piston?
@@the_retired_mechanic quite possibly, but it actually didn’t work out too bad. I was just a bit lost when I realised I had valve to piston damage. Most engines nowadays are designed to not bend valves or damage piston, due to softer rockers and cam lobes that will twist. Weirdly I had a slight blow by on no3 cylinder but it was small so I continued just on the off chance it was some sort of debris or carbon. It worked out anyway, thankfully 😅
you've got to be kidding me. The valves hit the piston, hard enough to brake the rockers and you cross your fingers that it didn't bend the valves or damage the piston to the point of seizing a ring land. The fact that it runs now doesn't mean that it's not going to score a bore with a stuck ring or burn a valve in the future. this is more of a get paid, cross your fingers, and hope it doesn't fail.
The rocker arms on this engine are designed to be the weakest they do not take much to break them to save the pistons and valves , piston and valves will be fine on this engine. although on some cars pistons can be damaged ford 1.8 tdci are known for this and will crack pistons if a belt snaps 👍
@@johnbickle4654 piston ring lands only have about 1000th clearance and even a minor dent near the land will seize a ring and damage the cylinders over time. my point is this is only a guess at engine life when the Pistons hit the valves at an angle hard enough to break the rocker there's going to be at least some bend no matter what. slow leak over time still adds up to engine failure eventually, and the cam-lobes are just press fit when they destroy a rocker they can slip time slightly. even using a Boreoscope would have been better than just a guess
@@JustMe-Dude your an angry person 😂😂😂😂 Valves are fitted in the cylinder head on quite a lot of modern engine designs vertical. (ie straight) This is done by designers to avoid valve to piston damage. This is the same reason that pressed on cam lobes can rotate. There is a percentage of chance in everything we do but we must weigh up the risk in order to avoid spending money that isn’t necessary. It takes years of practice to not allow it to upset us though. Thank you for the thought provoking comment though 🙏🙏
@@kennedysgarage3281 why would I be angry? that wouldn't help justification of a repair for either of us. and yes the valves are vertical but the pistons are not flat, they are cupped and only contact about 3/4 of the circumference of the valve, plus whatever carbon buildup is on the crown. my point was you have no idea if the valve was bent or not so only time will tell if there was enough damage to cause a failure later on down the road or not. personally I don't ever remember being upset about an engine repair in the 40 years I had been a certified diesel mechanic. but then I didn't do too many jobs where I just crossed my fingers afterwards to save a buck for the customer. if I didn't know something for sure I admitted that I didn't know. anyway I enjoy watching videos from different shops and different perspectives and often learn something in the process. it kind of also gives you an insight into the mind of the mechanic as they work out the process. hope it didn't upset you that I didn't just give you a wank in the comments like most do. I still prefer thoughtful dialogue or debate. your theory that the valves are vertical and the cam lobs are pressed is debatable for sure. engineers don't do that to minimize damage, they do it because it is cheaper to build...

Really enjoyed the 3 video, brilliant diagnosis and repair,

U done well mate!

Nice work. That's know how .cheers we all do our best 🍺

Great work mate

Great result Peter another great video.👍🔧

First class job.

Really, great job, Peter.

Mazda dearth. The Mazda content volume did slow thankfully. And did stop me bidding in trade at any SkyActive Ds for stock. A good thing
