611 Posted February 21, 2012 Author Share Posted February 21, 2012 Nice one, i went to take the head off today and found out they are different to the 2.0l that's on there, how disappointed was i :-( Thanks Andy Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted February 22, 2012 Share Posted February 22, 2012 Andy Don't bother buying any, they are stretch bolts and are crap DO NOT RE USE!!!. Use the 1.9 or 2.0 type asd they are a bog std high tensile bolt, either cap head or a multi point star drive. Look for 12.9 on the end of the bolt.

611 Posted February 22, 2012 Author Share Posted February 22, 2012 Hey Chris Thats good to know, so just use the ones i took out of the 2.0l head? they are the star drive head. I did drop you a message, as youcan probably tell from this post the 2.4 arrived on friday afternoon. i went to take the head off an discovered they are one of those new shape heads on the bolts from the 2.4. Is there a good way to get themout without having to buy a drive just for them? especialy if im not going to need to re-use them. I took the spark plugs out and they look a good color, so i just need to get the head off and see what condidtion the valves and pistons are like now and then i can start theswap over. Do you know where i can get the camshaft bearings from? kent have all the springs, lifters etc.. instock so i will be geting those ready to rebuild the head and have found some new rings and main bearing for the block so will get those soon as well.

lamchop77 Posted February 22, 2012 Share Posted February 22, 2012 Andy Don't buy anything until you have the engine apart. The 2.4 are notorious for wearing the bores at the top as i have mentioned to you previously, if that is the case the pistons will usually be scrap as well. Wossner pistons are the replacement to go for. Not sure where to get cam bearings from other than Risse, they should be available here but i dont know where. Also they need line boring so you need somewhere that can do that. Dont replace unless you really have to. Where did you find the mains from and how much are they? I have found that most engines have very little wear to the bottom ends so make sure that you know which bearings go where as they tend to be fine for road use. I only replace mine due to the fact that the engines are race motors. Take the pistons out of the bores and check the top ring groove there should be a max of 0.1mm gap between the piston and ring, they do wear quite badly on the 2.4. Just buy a cheap kit with the torx bit in it'll undo 10 bolts. Yep just use the 2.0 ones. Cheers Chris Quote Link to comment Share on other sites More sharing options...
611 Posted February 22, 2012 Author Share Posted February 22, 2012 Hi Chris I was going to go for a complete strip down and look at how things are before buying anything. The oil is very black so i dont think it was changed that often! Montza sent me these links for rings and bearings http://www.ebay.de/itm/Hauptlager-Glyco-CIH-1-6-2-4-Kadett-C-Manta-A-B-Ascona-/310358751120?pt=DE_Autoteile&hash=item4842d2b790#ht_3329wt_952 http://www.ebay.co.uk/itm/Vauxhall-opel-2-4-3-0-Frontera-Omega-Senator-C24NE-C30SE-Engine-Pistons-rings-/270904980245?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3f1331f315#ht_1339wt_952 I was thinking about changing any bits i could while its all apart, and was going to sell my head to help fund it. What do you think it would be worth without the cam? Andy Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted February 23, 2012 Share Posted February 23, 2012 Andy I think i would go to risse for the bearings, they were definately cheaper than anywhere else i looked. Price inc the 19% vat rate for germany and postage from them was 29 euros. As for the head its what you can get for it. Cheers Chris Quote Link to comment Share on other sites More sharing options...
611 Posted February 23, 2012 Author Share Posted February 23, 2012 Hey Chris Thanks for all the info, i have the head blot extractor now so the head will be coming off tomorrow morning so i guess i will know what i need then ;-) Thanks Andy Quote Link to comment Share on other sites More sharing options...
