Hi My 1998 jdm impreza wrx sti has developed a lot of noise from the offside rear wheel, I suspect bearing failier. the question is. Is it a fairly simple job to remove the hub and press out the old bearing, and press a new one in ? Cheers Steve,

Well I bought a set of plugs, and some injector cleaner. Decided to use the cleaner first to see if it made any difference and after adding it to a couple tankfuls the problem has gone!! Will fit the plugs at a later date. So all good.. Cheers Yoss.

Cheers will pick some up tomoz..

Yeah I will change the plugs, its got Iridium ones in at the moment. (not a great fan of those) but shall fit normal NGKs and see how it goes. Thanks Yoss

Hi everyone I have a imported 1998 Version 4 imported STI 4door, i have developed a misfire between 2-4k rmp on full throttle, seems to occur on full boost and clears once above the effected rev range. once above 4k it pulls like a train but it seems to drop into a misfire whilst building boost. Ive cleaned the MAF/checked all silicone joiners, it has got iridium plugs/standard intercooler/standard recirc BOV and Ive cleaned all of the visible electrical connections. Any suggestions/common failures?? it has covered 160,000 miles with replacement head gaskets/skim heads 4,000 miles ago. never had any running issues before and i am scratching my head as to why its happening now! Cheers Yoss

Well the engine went back in, and is sounding sweet!! Took it for MoT today and Passed! So all good.. Thanks again to Savage Bulldogs for all the help. Cheers Yoss.

Thanks the clutch is now OK. But time has flown by and haven't got on with it much. Next question. Cam sealing. Have put in new oil seals, Do I put any sealant under the the first cam bearing/seal cap? Don't like doing it. But some forums say its needed,and its easy to do while the engine is on the bench.

Yeah I think so!! It looks as though I need to remove the clutch cover. Is that right? if so I will have to make up an alignment tool.

Engine should be going back in this weekend if all goes well. what is the correct method of refitting the clutch fork and pin? The thrust bearing seems to be attached to clutch on this model, all the online videos show a conventional setup. Probabley quite easy but want to make sure before I have to lift the engine in. Cheers Yoss..

Yeah thanks, I have looked on his website. has everything I need on it.. How do you go about getting the right thickness head gasket ?

Well things going along OK so far, heads are off ready for skimming, Bores look good, Bit of wear but No scoring! So just a matter of cleaning everything up. The toothed cam belt idler is noisy, so will need replacing. £20 ebay or (£165+vat dealer)... It had a new belt and tensioner not that long ago so that should be fine. Going to fit either Cosworth or Roger Clarke head gaskets, as much the same price and spec. So far So good!!

Well it didn't overheat just pressurized the radiator, lots of bubbles after a spell on boost. Had a sniff test done to confirm it. But.....it had new head gaskets fitted 4000miles ago by a "Subaru specialist" who to be fair had done good work on my cars in the past, but unfortunately is no longer trading. So decided to remove the engine myself with my sons help and take it from there. Thanks for your help, I shall probably be back for more..

Thank you very much, I thought it had to come out, but it seemed quite tight so left it alone till was sure about it..

I am removing the engine in my 98 jdm wrx sti (head gasket blowing) Do I need to remove the clutch fork shaft to separate the engine from the gearbox?.. thanks Yoss.

HI Fitted a new pump from Tuning developments, £65.00 on Ebay running fine so far, so all good!! Yoss.
