[TW]Fox;12913695 said:VANOS is very very reliable on the M52, failiure isn't common and even if you get a problem its likely to just be the oil seals - you can buy a recon VANOS for just £250 anyway, so its cheap and easy to fix.
What goes wrong? Loads - cooling systems are made of cheese, the engines will grenade themselves if they are Nikasil lined, the suspension will almost certainly need a refresh on whatever you buy because most people just dont bother so it wont handle at its best - so new dampers/arms/bushes/etc.
How much do suspension kit's cost?
Shouldn't most of the engines have been replaced anyway?
This is where they get pricey yes?
