help with engine change

middle of changing engines due to worn crank,knocking!,owner has brought me a an engine to fit,,,,this picture shows original engine,,what is that thing in red circle? the replacement engine has not got one or hole to fit too

 

thanks for now

i know what is.....EGR control valve and pipe going to head from manifold

can the replacement engine be converted to take egr pipe? what size is it and what drill bit size would i need?

 

thanks nic

replacement engine now sorted,,,drilled out in stages,8mm all the way thru and tap m20 thread down 17mm deep...just need to change over induction system

engine in car and running very well,,,no knocking,mint 😀....but do have minor water leak coming from hard pipe going to lower matrix inlet.i do have one from other engine to replace it

Well done Nic, top work 🙂

fixed hard water pipe,no more leaking coolant,owner is very very happy.engine sits nicely at 650rpm ish,very smooth and responsive....engine swap done.hopefully back on mine soon 😀

started to have a look at old engine,,front left piston knocking from big end bearings,this is the only piston thats has the knock.......fingers crossed it has not touched the crank,hopefully its all good

well ive split the engine and front left piston bearing shells are gone,so full set of con rod bearings are needed,,,,not sure about the crank bearings....heres a few pictures of crank bearings....any ideas if they are still good to use?    there was no play in crank before strip down

 I'd measure up the journals and see if they're in factory spec , If so  I think a new set of stock shells are under £100 .

Would be a shame to spend £1k+ on gaskets and a timing belt kit , just to end up with crank rumble 

think your right there,after a good clean they look worse,will look out for new shells and conrod bearings...but will be put on back burner
