the stig 0 Report post Posted May 20, 2008 Have run into a bit of a problem with my E30 Took it into Jeff Grey yesterday and one of my rockers has snapped. Quoted me at least $1600 to fix becasue they have do do cambelt and everything else at same time. They said the only way to snap the rocker is to hit the limiter? Here is the problem, 3 weeks ago Jeff Grey adjusted the tappets on it. They still were ticky when I got it back. Is there a possibility that they over adjsuted them and this is what caused the rocker to break? Such a pain as I have the Taupo driver training this weekend. Thanks in advance Nick Quote Share this post Link to post Share on other sites

Mike 1 Report post Posted May 20, 2008 No, you don't have to hit the rev limiter to break them, though it is normally how they snap. Depending on what rocker it is you may be able to do it with the head on, remove whatever is in the way and pull the rocker shaft forward as far as you can and see if the rocker could be slipped off. Or get real bodgy and weld the thing back up again, I've seen that done. It does sound a bit dodgy that it snapped pretty quickly after a tappet adjustment. You could try hit up jeff gray about it but would be very hard to prove anything. Quote Share this post Link to post Share on other sites

Dad has gone to hit them up about it, but I doubt they will budge. Anyway, will see if they can do it for any cheaper or I will be counting Taupo out ha. But hey, sh*t happens Quote Share this post Link to post Share on other sites
the stig 0 Report post Posted May 20, 2008 Does $1600 sound reasonable? Quote Share this post Link to post Share on other sites
3series 0 Report post Posted May 20, 2008 $1600 does sound reasonable. I'd broken a rocker before and had quotes much more towards the $2000+ to fix. Quote Share this post Link to post Share on other sites

Andrew 30 Report post Posted May 21, 2008 Just do it yourself - it isn't particularly hard and you could have it done in a day. I'm sure someone down there can give you a hand. Doesn't Doug have heaps of free time? Quote Share this post Link to post Share on other sites

skidz 196 Report post Posted May 21, 2008 PM me your address and I will send you a couple of spare rockers (I presume this is an M20 motor)? Quote Share this post Link to post Share on other sites
the stig 0 Report post Posted May 21, 2008 PM me your address and I will send you a couple of spare rockers (I presume this is an M20 motor)?Have got is sorted. Told Jeff Grey to get stuffed, they wanted $95 an hour. Went down the road to one of dads mates and they rekon they will have it done by Friday. Really appreciate the offer Skidz, but the people have allready ordered in one and it is due to arrive soon. So Taupo is sounding good at the moment, apart from filling up with 98 petrol! Thanks alot, Nick Quote Share this post Link to post Share on other sites

OLLIE 26 Report post Posted May 21, 2008 the rockers become quite work hardened and brittle over time, they can easily be over tightened when being adjusted and crack. It's not what you want to hear but i'd say when they set them at jeff gray they over tightened it and didn't notice that it had cracked. I broke one of my old rockers by over tightening it. anyway if it is at the back of the engine you can slide the rocker shaft a little way out the front and put a new one in without removing the head, otherwise your head has to come off. It's a shame time is not on your side, perfect opportunity to fully rebuild your head, new valve guides, seals, a polish, reseated valves and reset valve spring rates. maybe even a lumpy cam if you can find one.

the stig 0 Report post Posted May 21, 2008 That are pretty much doing a complete head rebuild. Its a pain it didn't happen about two weeks ago, other wise I would have organised a lumpy cam to be put in. So far they are putting in New Camshaft (otherone was slightly worn) New Distributor New Rocker New Seal New belt and tensioner New waterpump New Rotor A++ to Quality Auto Machinists in Hastings. Went and towed from Jeff Grey, organised all parts to be delivered pronoto, and have moved it to the front of the line. Jeff Grey's hourly rate worked out to be just under $110 (including GST). My dads truck mechanics are only $60 an hour, so they have a huge margin. Just a quick question, does anyone no if the 325 allready had a lumpy cam in? Doug rekons that Gus might have put one in?
