dozeydustman Posted December 27, 2018 Share Posted December 27, 2018 I can't help thinking you've got a bent conrod or crankshaft if you can't get a full revolution. If it turns after you've drained the sump it might be saveable, XUDs are still relatively common, I'm sure a decent donor unit can be sourced if it's totally borked.

D Spares & Tyres Posted December 27, 2018 Author Share Posted December 27, 2018 Thanks anyway. I drive a ZX Volcane through a floor once and locked it up. While still in the flood I removed the glow plugs and disconnected the air filter then turned it over til all the water came out. It drove home but vibrated. The next day it started ok, drive a few miles then threw a rod. When cambelts break on these it usually breaks the camshaft or it bends the valves or both. So, no idea what has happened here!

The point to this car is its original engine. At 282,000 miles this is the first time it's been apart. The rest of the car is quite tatty. Without the original engine it just wouldn't be the same.

dollywobbler Posted December 27, 2018 Share Posted December 27, 2018 Is it a 1998? There was a big batch of XUD engines that had a tendency to chuck a rod through the block. Is it possibly this has merely bent one? Link to comment Share on other sites More sharing options...

Is it possibly this has merely bent one? This cars on an L plate, pretty sure it's not one of that batch when it's 280K plus and the engine and pump have never been apart. As Cats says those pistons seem to be very much in the right position so very odd that the crank doesn't turn Link to comment Share on other sites More sharing options...

D Spares & Tyres Posted January 1, 2019 Author Share Posted January 1, 2019 Bloody nora. What was the cause of death- did you drive it into a flood or something? Oh, and when's the rebuild? Yes, came round a bend to find a large flood caused by a blocked drain. I was in quite deep before I could think about it so made the decision to carry on slowly, make a decent bow wave and get out of there but it just kept getting deeper! Rebuild starts this week. I have an old ZX Volcane engine that will donate its rods. It had a failed head gasket but the owner kept in running it til the oil looked like melted Caramac bars.

Asimo Posted January 1, 2019 Share Posted January 1, 2019 I've also ruined a French engine with flood water, so empathy! With that much damage to a connecting rod, I would be concerned about the crankshaft being a bit twisted as well. D Spares & Tyres 1 Link to comment Share on other sites More sharing options...
BorniteIdentity Posted January 1, 2019 Share Posted January 1, 2019 Mega chuffed to see this getting another roll of the dice. Some cars, no matter how ordinary to the ‘common man’, really do get under your skin. Good luck man.

Scruffy Bodger Posted January 1, 2019 Share Posted January 1, 2019 That particular ZX still had the standard air filter in the same stupid low down position the manufacturer decided to put it iirc, same as the 306's. Many have suffered an early demise due to that piss poor design. Link to comment Share on other sites More sharing options...

Asimo Posted January 1, 2019 Share Posted January 1, 2019 My worry would be because I don't have any useful experience but I can imagine the massive forces involved in squashing a connecting rod into a wiggle. All that torque from stopping the flywheel in a few degrees must have put one hell of a twist into the crankshaft!I don't know how to check a crank apart from getting some precision measurements made. Which is probably easy for an engine machinist to do and impossible for anyone else. Link to comment Share on other sites More sharing options...
Matty Posted January 1, 2019 Share Posted January 1, 2019 I'd imagine they'd run the crank on a dynamic balancer and check for vibration and for whipping. We work on much bigger stuff but that's my best guess. I don't reckon measuring lands on the crank would show up a twist in it Link to comment Share on other sites More sharing options...
Scruffy Bodger Posted January 2, 2019 Share Posted January 2, 2019 Go with the suck it and see. The cranks on these are really strong, Toms has made nigh on 3x standard power with a standard crank so fingers crossed You've gone this far after all. Something resisted enough to make that rod bend that much, weakest point and all that? Matty 1 Link to comment Share on other sites More sharing options...
Tigerfox Posted January 2, 2019 Share Posted January 2, 2019 Is the crank in the zx engine the same ? You could then replace all rods and crank in one go and possibly replace the shells if they are cheap. Link to comment Share on other sites More sharing options...

Scruffy Bodger Posted January 5, 2020 Share Posted January 5, 2020 Initially he'd got the timing a tooth out so stepped away from it for a couple more months. Went back to it afresh and the little fucker started straight up Hard to believe but that engine ran like a sewing machine with all those miles on it and had never been apart pump included before the mishap* with the water. That car has had such a history since I bought it all those years ago for £950, it'd be fantastic to see it clear the 300K mark! chadders, Sir Snipes, Dick Longbridge and 1 other 4 Link to comment Share on other sites More sharing options...
