rian Posted May 11, 2015 Author Report Share Posted May 11, 2015 (edited) Let us know how you go with this, I have a twinky that sounds like it has very similar problems. Must get back to it... Mudwasps! grrrr..!!! Have you confirmed fuel pressure at the rail? I messed around with this thing again this afternoon. Got a good battery, compression numbers are from 1st to 4th: Dry: 120, 70, 120, 120 Wet: 220, 240, 230, 240 I used a lot of oil... The weird thing was it fired up momentarily after the wet compression test, it did it last time I tried a wet comp test too. So I've decided it's the compression causing the no start condition. Either way 70psi is not good. So I decided the engine is coming out. Fuel sprayed everywhere when I pulled the fuel rail off so I guess there is pressure. I checked the inlet manifold for debris/mud wasps - was pretty clean inside. I managed to get the manifold and fuel rail/injectors off and tape up the holes before it got dark. I'll do the rest another day, I still don't know how I'm going to get the engine out, I don't own a crane nor anywhere I can hook a block and tackle. I might just get some mates together and lift it out with 2x4s and some rope haha Edited May 11, 2015 by rian Quote Link to comment Share on other sites More sharing options...
kickn5k Posted May 11, 2015 Report Share Posted May 11, 2015 Dude 120psi is fairly weak too. Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted May 11, 2015 Report Share Posted May 11, 2015 I don't own a crane nor anywhere I can hook a block and tackle. Hire one? Make up a timber crane, 4X2's will do but 43 would be better, 3 of them in a pyramid that fits over the engine bay with 3 horizontals holding the bottom of the legs in place. Stripping the motor in place and lifting the block out with mates is fine, but its nicer to put a complete motor back in. Here's ideas- https://www.google.com.au/search?hl=en&site=imghp&tbm=isch&source=hp&biw=1144&bih=858&q=wooden+engine+crane&oq=wooden+engine+crane&gs_l=img.12...1276.4682.0.6660.19.12.0.2.2.1.600.2551.2-1j4j1j1.7.0.msedr...0...1ac.1.64.img..13.6.1946.WIPcpBkT1Wc Quote Link to comment Share on other sites More sharing options...
B-Lugg Posted May 12, 2015 Report Share Posted May 12, 2015 Look for dudes on Gumtree for a crane. I hire one from a guy that's local for like $20 bucks every time I need one. Also, I don't know where you're at but if you need a hand, let me know. Quote Link to comment Share on other sites More sharing options...
ke70dave Posted May 13, 2015 Report Share Posted May 13, 2015 So strange to lose compression like that, but the results don't lie. You said it like came to a grinding hault while driving? Weird. Quote Link to comment Share on other sites More sharing options...
rian Posted May 13, 2015 Author Report Share Posted May 13, 2015 (edited) Dude 120psi is fairly weak too. Yeah it's pretty sad, minimum allowable compression is like 125 PSI according to the manual. I'm still surprised it won't even fire on 120 PSI though. Hire one?

Also, I don't know where you're at but if you need a hand, let me know. That's a good idea, I could hire one. I just discovered my brother owns one but he lives 2 hours away, I might make the drive. So strange to lose compression like that, but the results don't lie. You said it like came to a grinding hault while driving? Weird. Yeah it's really weird, one day it was running sweet - would rev to ~8000rpm and felt really strong. The next drive it just wouldn't rev properly at all, as soon as I started it it was running weird and anything passed 1/4 throttle would make it splutter and misfire. The next time I tried to start it it wouldn't go. There was a few weeks between when it was running perfectly and the first time it wouldn't start, but there was only one drive in that period - it literally went bad in zero running time.

rebuilder86 Posted February 26, 2016 Report Share Posted February 26, 2016 Sorry to div up an old thread but i was reading this and thought of 2 things, all valves locked up, and a cracked compression ring. Which was it? Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted March 7, 2016 Report Share Posted March 7, 2016 True- Its annoying when you're hunting down a similar problem and all the suggestions come in, but no-one tells you what happened!! C'mon Rian, what did you find?? Quote Link to comment Share on other sites More sharing options...
rian Posted March 16, 2016 Author Report Share Posted March 16, 2016 Sorry to keep y'all waiting. I pulled the engine down and everything was intact and clean, the engine just didn't have enough compression to fire. The new engine went in and fired straight up on the same wiring loom and ecu that was running the old engine when it died. It was pretty weird that it lost compression within about a minute of actual driving time. Quote Link to comment Share on other sites More sharing options...
LittleRedSpirit Posted March 16, 2016 Report Share Posted March 16, 2016 Thats very odd. You found the limit. :clover: Quote Link to comment Share on other sites More sharing options...
