Exclamation alfa romeo 2.5 v6 timing lock issue

Hello every one,


i am wondering how you guys set the timing for your v6 engines correctly ? i have ordered many cam locks starting from the red ones on ebay and they did not work or fit correctly ending with this one from ebay and it is expensive, and the seller told me he is working with it for 20 years..... so i ordered it from him and happend what i was afraid off... it is rubbish

https://www.ebay.com/itm/Alfa-Romeo-...l/152128999782

so can someone help me with trusted website that they sell a properly working locks ? ?????

Did you try them ?

The car idling is rough after using them, we have another engine that has factory timing setup and never was touched, we tried this cam locks on it and did not fit at all and has different sides

Ok, a quick search tells me that you are right, those cheap versions are wrong. https://www.alfaowner.com/Forum/alfa...-required.html (2.5 V6 - Cam locking tool info required)

Only use OEM Alfa locking tools, others is a waste of time. Ask on the forum, maybe someone can borrow you a set.

I cant comment how you are using them but I'd be suprised if those were wrong. Alternative Autos have been supplying Alfa (& indeed Fiat) parts for years (certainly as far back as the old Alfa156.net website) and the owner Steve is pretty clued up on what works and doesnt work.
He is one of the suppliers I'd trust along with Shop4parts, Alfaworkshop etc.

This is the kit I am using this moment. I know that timing is spot on using it.

Just get a set from E. B. Spares. They have only been the game for centuries - well it seems like! They also hire them out.

Definitely wrong!

You have inlet and exhaust on #1, exhaust on #4 and inlet on #6. Your exhaust cam is about 180 degrees out on the front bank, the exhaust lobe should be upwards on #4!

Iíve put them on back to front as well - I can only recommend turning the engine over by hand many times before thinking youíve got it right!

I know, you are right. It even says cylinder 4 on the front lock. I am so glad I posted the picture so that it was caught in time

Thank you!

Looks like it's quicker, more accurate and safer to use Tippex!

I donít know how people get it right with tippex. Itís hard enough doing it with the cam pulleys loose so you can get the tension right....

Yeah, that stuff.

Other than getting the tension right, the biggest problem is the assumption the person who did it last time got it right....

That makes me happier!

The blocks I have donít have the arrow - my 3.2 ones are TotallyAlfa replicas. The instructions are clear, but you have to read them ... so when I rebuilt my GT 3.2, rather than locking the lobe on the left of the bolt, it locked the one on the right - so about 45 degrees out. The engine turned half a revolution on the crank nut before locking up - I then managed to work out what Iíd done!
