lobotomy Posted August 29, 2007 Share Posted August 29, 2007 I tried toyota for new leads mate -- got a similar quote but I'm sure it was about £90 with the king lead too.Get some magnecors for the same price. Quote Link to post Share on other sites

scutch0 Posted September 8, 2007 Author Share Posted September 8, 2007 theyre genuine toyota denso's for the 4efte.anyone know what size gap the plugs should have? as i tried a 1.00mm feeler guage on one and it just fell thru it??my guess is thats the gaps are at 1.10mm.

Glanza_Ragger Posted September 10, 2007 Share Posted September 10, 2007 From the pics of the original plugleads it looks like water has lay in the sparkplug chamber for an extended time. It's common for this to happen as the seal isn't great on the pluglead. (Magnecor actually provide water repellant gel with new leads to prevent this issue)Because the chamber is a closed enviroment the water gets heated and cooled repeatedly allowing it to penetrate and corrode the plug, the leads and the threads. The spark generated is affected by the moisture and leads to misfiring. Normal procedure is to replace the leads, the plugs and ensure there is no remaining damp left in the bore. It's a common issue that occurs if the engine is steamwashed, operated in heavy rain conditions or excessively subjected to H2O in general.Replace those plugs mate.Hope this helps.Nicely said Jay.I thought they were new plugs too Rich?

scutch0 Posted September 10, 2007 Author Share Posted September 10, 2007 what the reference code for the ngk iridium tipped plugs for the 4efte? as i might be able to get a set cheaply thru work. Quote Link to post Share on other sites
scutch0 Posted September 11, 2007 Author Share Posted September 11, 2007 awesome thanks alot jay. youre a legend. thinking back they were probably changed about 4-5 months ago, so they could probably do with being changed anyway.well mine sounds like its running rough all the time, but i just assumed that that was the exhaust with just a rear can and no cat... but i could be wrong? bit of a random question, but did yours idle ok on three? i got overtaken by another glanza earlier... which was standard, so somethings defo not right. i have faith in what your saying jay, but... if this doesnt work where do i go from here?as i dont really want to get it rolling roaded if theres something internally wrong.

Glanza_Ragger Posted September 12, 2007 Share Posted September 12, 2007 Compression test ...Cost you about £15 and should give you an idea of the health of it bud.Exactly what have you got fitted ? Quote Link to post Share on other sites
scutch0 Posted September 12, 2007 Author Share Posted September 12, 2007 ok i got some good ngk plugs in there (non iridium) and it feels a bit better again, i havent had a good chance to test it but it still doesnt feel like its made a massive difference.i rang toyota and it turns out that the gaps should be 0.8mm and my old ones were at 1.10mm! so it is probably doing it some good.i was actually looking at a compression tester at work today, i think i'll get it tomorrow and give it a go. my full spec is as follows:k&n panel filtergutted cat2 1/4" straight through to the backbox exhaust systemboost contoller running .8bartype rs bovparts replaced:oil and filter change every 6k (ish)fuel filterintercooler hosesdizzy caprotor armclutchleads plugscheers again guys!

scutch0 Posted September 13, 2007 Author Share Posted September 13, 2007 ok, as previously stated, it does feel a whole lot better, but still doesnt seem as quick as i thought it would be.compression test later this week. Quote Link to post Share on other sites

lobotomy Posted September 13, 2007 Share Posted September 13, 2007 i think mines is overfueling aswell tho lol, after my glanza's bn allowed to 'stretch its legs' i get a nice big wiff o optimax lol, not too bothered about it cause it means that my pistons aint gonna turn into jelly lolJust read this -- Running slightly rich will cool down combustion temps, but running overly rich can cause problems too like borewash and in the end perhaps ring and piston failure too! I wouldn't take it to be a good thing! That's why you should really get things like RRFPR's set up on RR's! Quote Link to post Share on other sites
scutch0 Posted September 18, 2007 Author Share Posted September 18, 2007 what reading should i be getting from a compression tester on a good cylinder?whats the compression ratio on the 4efte? Quote Link to post Share on other sites
Glanza_Ragger Posted September 19, 2007 Share Posted September 19, 2007 what reading should i be getting from a compression tester on a good cylinder?whats the compression ratio on the 4efte?Ratio is 8.2:1 off the top of my head..170 on each cylinder should be a very healthy engine.But it can range from 130 upwards depending on the condition of it Quote Link to post Share on other sites
scutch0 Posted September 22, 2007 Author Share Posted September 22, 2007 compression test has been put back a few days, i'll post what my findings are when i know. Quote Link to post Share on other sites
scutch0 Posted September 25, 2007 Author Share Posted September 25, 2007 ok guys, the compression test came back ok!all cylinders holding 12 bar of pressure (170psi)so what next!?my dad recons it could be a tight valve, is this something quite common? Quote Link to post Share on other sites
Glanza_Ragger Posted September 25, 2007 Share Posted September 25, 2007 ok guys, the compression test came back ok!all cylinders holding 12 bar of pressure (170psi)so what next!?my dad recons it could be a tight valve, is this something quite common?Hmm, 170 across ..Should be running spot on then dude.Cant you get it rr'ed?

Glanza_Ragger Posted September 25, 2007 Share Posted September 25, 2007 Going a bit deep to be honest lads, simple things are always the route of it, look how basic it was to tidy up the idle, plugs were corroded and leads were letting in water........not jumping in with MAP sensors and thermostats. Now we're onto tight valves? Do you know 100% its overfuelling? Have you had it on a 4 gas analyser yet? To tell you whats coming out the exhaust?I still suggest he gets it on the rollers Quote Link to post Share on other sites
scutch0 Posted September 26, 2007 Author Share Posted September 26, 2007 well i had it mot'd a few months back which it failed to very high hydrocarbons i was told this was overfueling.plus when driving, if you stop at some lights for instance you smell fuel, really strongly, plus when booting it loads of black soot comes out the exhaust ( ive been told this is another sign of too much fuel) plus i get loads of black spatter on the rear bumber.as it looks like there is nothing wrong internally i'll consider getting it rolling roaded.but in the meantime can anyone suggest anything else?

scutch0 Posted September 30, 2007 Author Share Posted September 30, 2007 ok, it popping out the exhaust really bad now... wouldnt be surprised if it was popping flames for the amount of fuel i can smell.is there anything else anyone can suggest to check? Quote Link to post Share on other sites
scutch0 Posted October 1, 2007 Author Share Posted October 1, 2007 ok mate. thanks for the advice. i think i'll be going to see mr burwash before xmas! Quote Link to post Share on other sites
