Drove the car down to see Paramedick to try to diagnose the ticky tick thumpy thumpy I have been having.
ticky ticky was heard at any rpm over about 1300 and was def worse when the car was in overrun like coasting downhill in gear.
thumpy thumpy has been recent in the last two weeks or so when taking off in first gear you can feel a rythmic something thru the clutch pedal taking off and had been concerning to me lately.
the car has also been puking oil out of the rear main seal and the brand new front crank seal (like less than 1k miles old) everywhere it goes.
Arrived at Bruces Place Thursday night after a 3.5 hour drive, parked the car in the garage for cooling off and got at it in the morning.
First thing we did was pull the glow plugs and check compression.
#1 440
#2 450
#3 450
#4 440
All are great for a car with 143k on it.
after that, we swapped in a used set of stock injectors he had. fired it up, noise is still there. ticky ticky when reving, thumpy thumpy when loading the clutch.
borrow a snap on boroscope, no dice, barely doesn't fit thru the injector hole, so we reinstall my sprints.
at this point, many phone calls ensue. deciding what to do. Bruce has a cam & lifters on the shelf, just in case there was something wrong with the ones i just put in when this issue started.
Bruce also has a complete rebuilt Franko6 head with 2 hole head gasket on the shelf.
after much debate, we decide to just bite the bullet and pull the head, swap on the good Frank head and cross our fingers.
once the head comes off, we decide to use bruces deck height gage to check the piston protrusion.
#4 comes up 39 thou above block
#3 comes up 40 thou
#2 comes up 40 thou
#1 comes up 30 thou..... Uhh wut?
after much rechecking,and cleaning the tops of the pistons (which look AWESOME BTW) we get the difference to be 6 thou instead of 10... which is still out of spec according to another call to Franko6.
Gotta pull the oil pan and pull the #1 & #2 Pistons & Rods and send off to Frank for matching... UGH.. moar money.. oh well, Im committed now.
After draining the oil, pulling the pan, calling my wife to let her know its not as cheap as a set of injectors... I come in and get told to go see Eric (korndawg, Bruces son) he shows me this, found in my Oil pan..
After seeing that, I committed to pulling all 4 pistons to see where the damage was if needed.
We pop #2 out first since its easiest to reach of the original 2 pistons we were pulling.
we then pop out the #1 piston and find out where thunk thunk was coming from.
here is what a good wrist pin should look like.
here is one where the brass retainer and the edge of the piston went out to lunch...
And here is what they had for their main course.. OM NOM NOM Cylinder wall..
in addition to all of that.. took a look at the inlet side of my VNT15, the turbine blades decided that they wanted to be a blender or something because every one of them had been chewed up around the outer edge of the inlet hole. (sorry no pic yet)
so ya.. see my signature. I need a longblock, top to bottom, front to back.
Yee.... Haw.
Bruce sent me home in his B4 Passat. He is a saint. Good Friends are priceless.
