leigh_harty 1 Posted May 27, 2012 Report Share Posted May 27, 2012 Put my pistons back in the block with new rings and conrod bearings and couldnt crank it over (by hand)Took them all back out to check the rings and their all finePut piston 1 back in (closest to belt) and tightened it up and the crank is locked again, loosened it and it spun freely, tightened back up and locked again? I could spin it with a longer bar but when ive just a second piston back in its very tightAny ideas? bearings oiled up, new ones looked identical to old ones etcOh and hello Leigh Link to post Share on other sites
UnitedMotorsport 55 Posted May 27, 2012 Report Share Posted May 27, 2012 Big end caps on backwards? Link to post Share on other sites
russj249 2 Posted May 27, 2012 Report Share Posted May 27, 2012 Big end caps on backwards?Don't the con rod caps have to go on with 3 arrows pointing to the gearbox, and 3 pointing to the aux belt side. When I changed to ARP con rod bolts I found that out. Couldn't turn it by hand and only put 1 on backwards Link to post Share on other sites
leigh_harty 1 Posted May 27, 2012 Author Report Share Posted May 27, 2012 I did have them on back to front yes.Made some progress thoughTook the pistons out a fortnight ago to do the rings unknowingly I needed a specific ring compressor tool. So tried various methods of getting the pistons back in failing and breaking my ringsSo in a rage everything got thrown in my boot unlabelled etcNow with my second set of rings and a proper vr compressor I've been putting everything in wrong place it seems Link to post Share on other sites

russj249 2 Posted May 27, 2012 Report Share Posted May 27, 2012 Ooh, mine had arrows on as well as a casting number. Odd. Link to post Share on other sites

Odd.[/quote']Yea maybe due to engine age?Do you know what the torque settings are for the caps > conrods & the caps > block are?Got all pistons in and spinning freely now just need to torque everything up then start putting new everything else back on Thanks, Leigh Link to post Share on other sites
UnitedMotorsport 55 Posted May 27, 2012 Report Share Posted May 27, 2012 The caps also need to go back on the exact rod that they came from. When you threw everything in the boot, did you at least mark which cap came from which rod? If you didn't that cant also cause an engine to lock up, it will also cause the engine to fail in only a few miles. Link to post Share on other sites

[/quote']Nothing was marked up because everything was organised on the floor in the garage, but after taking everything apart, realising i need a specific vr ring compressor & breaking my new rings i just give up lol... bad move hahaI eventually matched each one up (hopefully).. you could tell which one fitted well and the other 5 had play, something i didnt check 1st time roundBut good news, it may have taken all this glorious weekend but it fired up a charm, tappets are quitening down and she drives. Thanks for all the input guys really appreciate it, Leigh Link to post Share on other sites
