Genius. I had to do the same on a Citroën C4 120Vti. I made a similar tool to what you made and it worked like a charm. Thank you for the idea 👍

Your tip and a aluminum rod did the trick for me. I used a cutoff wheel to cut a notch into the end of the rod. I rounded the tip and extended the notch down the sides. It's a little more involved than your cutout, but i wanted to use something softer than steel yet sturdy. 20 to 24" long was ideal Thank you for sharing this and inspiring / helping people for years to come.

I don:t usually post comments. I was doing an N12, and the Valvetronic springs were giving me stress to insert behind the rockers. Having seen the fortunate people with a specific tool from across the pond made me wonder if I could source such a tool...... One sacrificed screwdriver and on long extension through the springs to pivot the screwdriver.... 15 mins to finish all 4. Thank you so much for sharing this video. Top Man!

Just about to tackle one of these and saw the price of the special tool now I'm a stickler for proper tooling but then i looked at the procedure and thought...surely there's a way round that, its only engaging a spring..let me have a quick look on KZitem and there we are 😄😄 great quick clear and informative video 👍👏

Great video. Thanks for the explanation. I'll be making that tool today. I saw how you had a little trouble with it slipping off of your special tool so I think when I make mine I'm going to file a groove into the back of the hook part to keep it from slipping off a bit better. Thanks again for the great video.

That's clever. Last time I undid the top bolts and reinstalled with a bar through the springs and two 8 ring spanners. Took 3 people to do it properly without cross threading the retaining spring bolt :)

Replacing the valve guide seals on the Prince engine is only half the solution to the oil burning problem. You really need to replace the piston rings as well. PSA/BMW in their wisdom decided to build the Prince engine with a one piece oil control ring which fails quite early in the life of the engine causing the 1 litre per 800/1000 miles of oil consumption. You can guarantee by the time the valve guide seals need replacing the oil consumption will be through the roof and the rings are shot. So better to remove the head, do the rings and cam chain at the same time. Bigger job, more money but the engine will last a long time after that level of intervention.

I have done a HUGE amount of these engines over the years and to be honest I have only seen the valve stem seals cause the issue, once they have been done it has solved the issue for all of the engines I have done the job too. I have never had to do the rings on any. Besides the cost of the job to basically strip the engine down and replace the rings ect would basically be on par with fitting a refurbished engine anyway.

Thank you for sharing it. How can i remove the springs.? Also with this Tool? Remove the spring Out and then loosen the screws on the top ? Is there a Video available where you remove the springs? Thanks
@Chris_CDB

When you remove the assembly the springs will pop out, (they will ping the rockers as you release them so be careful), but you could use the tool to release most of the tension if you needed to.

Great video, I need a question answered if i may, I have a 2009 base cooper, non s model, No compression on cyl 1. Engine has a rattle when running, Have looked and valves are not broken, bent? maybe? Could a failure in the vvl cause a valve to stick open? And would it make noise. just about to pull the head, it appears to have a burnt valve, but that doesnt explain the rattle? any help would be apprectiated. Also if you pull the spark plugs out there is no rattle? crazy i know .

Hello there, this is going to sound ridiculous, however I have a mini in the workshop (non s like yours), which had an issue and when looked into the problem was inside cylinder number 1… when the valves were looked at the number one cylinder had one valve that was lower down that the rest with the camshaft removed… suspecting a bent valve I removed the head, only to find that the valve seat had come out of the head and somehow was wedged at a funny angle… I have never seen it before, only quick solution was a new head, now your rattling could well be a similar symptom to what this one had, as the valve was not heigh enough it would rattle the lifter against the cam…. Grab all the lifters and give them a wiggle, you should not have “play” between the lifter and the cam. If you have then you may have a similar issue!

I don't think that you need locking tools to do this either as long as the chains still on etc

You 100 percent DO need the locking kit, you will never get the cam in the correct place if you don’t lock it via the tools.

Would it be better to leave a small hook section on the bottom so the spring can be moved back and forth with the driver and side side? Once in place just push the driver forward and then pull it out? Just curious, as I'm about to embark on this journey soon..

So I am understanding. You are seating the VVT spring before dropping the rockers and cam shaft into place, and then carefully fitting everything down on top of the VVT spring? My son and I are about to do valve seals and timeing chain on his 2010 N12 motor.

You need to bolt down the cam down 1st and leave the springs until it is all tightened down, basically you want to lay the cam and vvt spring assembly down onto The rockers and tighten it up then do the springs last.
