NuclearBacon Posted July 10, 2005 Share Posted July 10, 2005 What you are about to read is a mystery..... If you choose to read the following and help solve the mystery, it will propel this young man, into the SCCA rally field... and onto certian glory... These are FACTS about my mystery. These FACTS have been proven unless stated otherwise.... EA82T engine missing on Cylinder 1. Switched the injectors from 1 and 3, still missing on 1. Switched the spark plugs from 1 and 3, plugs sooty all around, still missing on 1. Noid light on injector lines, firing. No problem. When you pull the injector wire, there is a slight notice in running (as in it runs worse, but only slightly worse), not as bad as when you pull the plug on any other cylinder..... and when you pull the spark plug wire off the #1 cylinder, there is no noticable change. Spark is reaching the spark plug.... timing was checked and is WAY off.... when distributor is retarded full, the engine runs best, when anywhere close to normal, engine runs poor... when injector fuel lines were removed to switch injectors, there was pressure. fuel was also in both lines, giving me the impression that fuel was passing through the injector, and when the injectors were switched, the miss stayed at cylinder #1 I'm thinking flat cam, or something to do with the rockers?? i read in both chilton, and haynes about that, and i ordered the "Subaru repair guide for the complete idiot" book, i heard on here its a good book to have, so i thought i'd take it upon myself to order, should be here any day. but i am at a loss.... I can't really think of what it could be.... besides timing, and could it be that its all it needs??? broken tooth on the timing belt? but then why is the missing #1, still missing, and only that wierd way?? The engine is telling me symptoms for something i cant read..... any ideas?!?!?!?!?!?! !!!!!!!!!!!!!!THANKS!!!!!!!!!!!!!! Quote Link to comment Share on other sites More sharing options...
TomRhere Posted July 10, 2005 Share Posted July 10, 2005 Possible blown HG, pull a compression check. Also, could be one of the rockers fell off of the HLA for that cylinder, pull the cam cover off and take a look. Happened to electryc_monk.

555Ron Posted July 10, 2005 Share Posted July 10, 2005 What about the basics? Switch the spark leads around (on dissy and plugs!). Check rotor to cap connection on 1. Then check the valves by feeling for them while turning the engine slowly. From there i think it gets complicated. Quote Link to comment Share on other sites More sharing options...
oddcomp Posted July 10, 2005 Share Posted July 10, 2005 my first guess would be maybe the belt on that side is a tooth or 2 off thus killing your cam timing and as a result your compression and drivabilty ect my second guess is someone put the distributor in 180 degrees out exactly opposite from where it should be lined up the motor will still run but run like crap won't it hondasucks... hehe now as far as a miss on a certain cylinder a valve could be hung open or you could have bad rings on the cylinder and low compression or a blow headgasket Quote Link to comment Share on other sites More sharing options...
NuclearBacon Posted July 10, 2005 Author Share Posted July 10, 2005 compression is up on all four cylinders.... Distributor to Rotor to cap, everything chcks out in that department... remember, i'm getting healthy spark. TomRhere.... good idea about pulling the cam cover off... i'll look into that... 555ron.... i'll check the valves by feeling them... any tips on how to do this??? OddComp..."my first guess would be maybe the belt on that side is a tooth or 2 off thus killing your cam timing and as a result your compression and drivabilty ect" "my second guess is someone put the distributor in 180 degrees out exactly opposite from where it should be lined up " these are all great ideas.... i'll go through them, and let you know...

Skip Posted July 10, 2005 Share Posted July 10, 2005 1) you don't tell us what MPFI system you are running I see mention of an 87 so it might be the hot wire not vane or flapper door 2) Sooty plugs =.> from a rich mix or poor spark or wrong range plugs. They are NGK BPR6ES-11 no doubt? 3) I would like to read what the comp psi/sq in is in number 1 ...not "it's up" ... bit nebulous to my feeble gray matter 4) I will assume you had the green test mode connectors together when you looked at the timing at idle. Has the distributor been out of the engine? 5) You have obviously swapped plug wire three with plug wire for one ( they both reach the dist and can be changed) 6) Have you ever heard of "Colortune" a clear headed spark plug to let you watch the combustion http://www.international-auto.com/index.cfm/fa/p/pid/3448/sc/8189 7) a vacuum leak in the intake runner to number one may lean it's mix to a non fire situation BTW Your hopes that the Keep your Subaru Alive book will help is not based on fact - in fact it has very little on the turbo system. Children's and Underwear manuals are also not much help as you noted. Shop the Bay of E for a FSM if you want to get the true skinny Feel free to answer any of the above questions or to ignore this convoluted inquisition Quote Link to comment Share on other sites More sharing options...
Ross Posted July 10, 2005 Share Posted July 10, 2005 Don't rule out a bad spark just because you can see a spark at the plug with it removed. Conditions are very different in your engine, spark may not occur when under these conditions. The fact that turning off #1 plug makes no difference while the injector does seems to point to a spark prob. Quote Link to comment Share on other sites More sharing options...
[HTi]Johnson Posted July 11, 2005 Share Posted July 11, 2005 Have you replaced the plugs? Quote Link to comment Share on other sites More sharing options...

tizzle Posted July 11, 2005 Share Posted July 11, 2005 my second guess is someone put the distributor in 180 degrees out exactly opposite from where it should be lined up the motor will still run but run like crap won't it hondasucks... hehe I can also vouch for that Quote Link to comment Share on other sites More sharing options...
jeffast Posted July 11, 2005 Share Posted July 11, 2005 check for arcing the easiest way is to drive to a parking lot or back street with no lights then open your hood and watch the wires to see if it is going around the boot my friends gl was arcing around the boot to the block Quote Link to comment Share on other sites More sharing options...
MilesFox Posted July 11, 2005 Share Posted July 11, 2005 i'll bet someone installed the timing belts wrong. run through the algnment procedure per the usrm> engine (sorry the pics are down but the text will help just as well) Quote Link to comment Share on other sites More sharing options...
NuclearBacon Posted July 17, 2005 Author Share Posted July 17, 2005 well!!! I took the valve cover off and BOOM! out comes 2 ...count them... 2 PIECES of a hydralic lash adjuster and a rocker.....on the intake side. so!!! Can a new hydraulic lash adjuster and rocker arm be installed without removing the cam? Is there enough room to install the lash adjuster in its hole, collapse it as far as it will go, then slide the rocker arm in place? i was thinking about loosening the cam...then sliding it under and popping it in... good? bad?

NuclearBacon Posted December 12, 2005 Author Share Posted December 12, 2005 i was thinking about loosening the cam...then sliding it under and popping it in... good? bad? break loose the cam part of the head from the head part of the head, and use a thick grease to hold the lash adjustors in place... then rock the head back over... and all is well.. worked great!
