Nissan Largo Friends

Hi ya all I have just brought my 1st Largo highway star.
It has very severe bottom end knock so im going to take the sump off and see whats going on. I know nothing about these engines is there anything that is common and I should look out for, also I should add its a 2.0 diesel 4wd done 70k I have no idea why its knocking I brought it like it and fancy abit of a project. I have sourced another engine but would rather repair this one. Im also very sorry in advanced for my poor spelling and gramma im dyslexic.
Thankyou very much for your help Harry from devon

Hi and welcome along to the forum, look on here the cd20 i think from a primera will fit look up on the search it would be more economical to do a swap than try to buy the parts and rebuild the one in the bus..
Enjoy the forum and the Largo..
