After reading many posts about replacing head gaskets I still have a few questions. Here is a little bit of background about my problems: In August my engine overheated and I took it into a shop and they found the problem to be a loose connection that I was loosing coolant out of and I simply ran too low. They pressure tested everything and told me that my block and head gaskets were fine. However, recently i started hearing the whooshing water noise that people talk about underneath the dash and I became concerned. Sure enough my oil is foamy and I will be replacing the Head Gasket. I am a college student and cannot afford to have the work done so I will be towing the car home over Christmas break to try and do the work myself. So finally my question is, do I need to have the system pressure tested again to ensure that the block is not cracked? Also, how do I know if my heads have been warped from previously overheating?

My Disco had 118K miles on it and while I have everything torn down I was planning on doing some preventative maintenance, here's what I have on the list so far:

new water pump
resurface heads
timing chain

On my last major meltdown I had the plugs and wires replaced with heavy duty ones and a new serpentine belt installed. Thank You for any advice

 

Send me your tele number and I'll be glad to help you get past this issue.

You dont need to replace the timing chain.
