Tein Coilover Noise Weird Red Lumps

[Mick]

hey i have tein hr coilovers in my r33 gtst and one of the back ones started making a loud squishy sound when i hit a bump, its like i can hear it working loudly and i got a loud knock noise from it last night so i decided i better check it out, i was wiping the rubber boot on it and when i moved it up these soft red lumps were under the boot at the bottom, im assuming they were a bump stop at one stage?

what can i do about it, can i buy a new bump stop if thats what it is?

would this make the noises

Yeah there's a donut shaped bump stop that sits around the piston under that boot. You can buy new ones and IIRC the ID seemed like the important dimension when i replaced the ones in my teins. I went to the local pedders and went through their box of odd used but serviceable ones, choose something that looked about right then trimmed it down to the right height with a hack saw.

Loud squishy noise could be a mix of air and oil going thru the valves since some of the oil has leaked out. Any signs of leaking? Anyway after you pull it out move the piston fully out then fully in to how it feels.

yeah does anyone have a left rear tein hr coilover, doesnt have to have the spring, its obviously damaged and i thought some one may have an old one from a wreck
