fullwavebridge Posted August 23 Share Posted August 23 Just a follow up really after i replaced 2 glowplugs last week. I still had quite a bad problem with starting regardless of weather or temperatures hence the reason i replaced two faulty glowplugs. Discovered head was wet, and very black, gunked and was chuffing with bad injector seals. In for a penny in for a pound, ordered new leak off hose kit, injector seals and rocker gasket. Whipped top end off, including top cambelt cover to reveal a mountain of black lava caused by the carbon gases making good friends with the oil and diesel. Scraping this off was horrific, tip.... get as much off as possible before removing injectors. Did 1 at a time, fill the injector bore hole with a bit of clean rag , the plastic collar on two of my injectors had vapourised / melted into the bore and scraping it out was difficult. I used a 17mm x 17mm bore cutter to lightly cut new seats before the injectors and copper seal washers went back in - apply grease to the cutter so the swarf sticks to the tool. My screwfix titan wet n dry vac was invaluable - i only bought it for cleaning the log burner and after i sweep the flue liner ! sucks all the crap out of the top end, but better is the pipe on this model can be fitted to the vac out let and becomes a powerful air blower torque setting for injector clamp bolt is 15nm + 70 degrees more - my torque wrench doesn't go that low so i had a guess at 26nm. Whilst i had better access i replaced the other two old glowplugs which tested ok last week and i bought a set of 4 anyway. Quite easy to remove imo with a small 1/4 palm ratchet and 8mm socket, complemented with a tin of plus gas. The worst scary thing is what caught me out previously where you get all the thread out but it still wont come out - for me i kept turning them whilst spraying the plus gas and they came out fine. getting top end back on is awkward and i had to reconnect egr pipe to top cover first, then pushing it down to inlets with new lubed o ring seals wasn't easy either. compression is back up, no chuffing yet ! runs much better and starts easily now so it was probably poor compression. Some people say the injectors are only powered when temps are down to zero etc, that i found isn't true as i tested the glowplug relay previously - in my case they come on for 3 seconds regardless. Got a couple more jobs to do, it's like a bad dose - the gift that keeps on giving....... 3 Quote Link to comment Share on other sites More sharing options...

Well you could give it a try, I didn't know a glowplug would fit in the injector hole 🤣 Don't you just hate it when you can't edit or delete something 🤔 1 Quote Link to comment Share on other sites More sharing options...
