AMF Injector & Tandem pump replacement,

Hi Keith. No visable sigm of damage with the sump off however their is another cover within the sump so can't see the bottom of all the piston arms. I can also see small bits of metal debris so I'm presuming whatever it is, it's been pulverised quite badly!
It does fit together however not a lot left.

Matt,
Was the car running when you acquired it, had it suffered cambelt failure or oilpump chain issues etc?

Keith.
Hi Keith. The car was running & the only issue was Diesel leaking into the engine. Had the injectors checked out & they are fine so replaced the seals but also replaced the tandem fuel pump. Previous owner said no other problems other than the Diesel getting into the engine.
 
As Keith has said can you piece together the bits? Looks like a flange around the edge. What condition is the oil cap in? Do you still have the rocker and sump off? You could use a portable endoscope to check the engine over especially the area within the sump. Try to retrieve as much as possible. Is it magnetic? Have a good look at the pistons both upper and lower ends. How much history do you have on the car?
Hi.
Posted a pic & what's left does fit together...any ideas? Oil cap is fine. Rocker & sump both of, yes & I've just ordered an endoscope & thinks for the advice. The debris is magnetic, yes. I have little history but the cambelt was done a couple of years ago & not failed.
 
Not much to go on but best guess is a valve spring cap - Item 12

Cheers Spike
Cheers Spike. It could explain the leaking diesel! I'm going to remove the head & investigate further. I have recovered about 1/5 of the cap (if it is that) & the rest looks to have been broken up by the engine. I threw the oil filter away a few weeks ago & so can't check for missing peices. The gauze lifter looks to have kept these bits from re entering the main body.
 
Also think item 12 being prime suspect. Would not immediately take the head off. Take the cam off then take out each tappet in turn. If it is the cap it will be pretty obvious. Replace parts as needed and blow out as many air and oil passages through the block and clean the sump pan. Rebuild and with rocker and sump off rotate the engine a couple of times, but i suspect this has happened a while ago. If all good, rebuild rest after doing any other jobs you have planned or needed. New oil and filter. Use the car carefully for a few hundred miles. Drop the sump again to see if any more bits generated. If not good clean out again refit sump and new oil and filter again. Use the endoscope wherever you can, some even come with a magnet you can clip onto the end to help retrieve bits.
 
Matt,
In photo 3 can you take a shot of the piece next to the 20p

Hi Matt ,
Having just rebuilt my engine following cambelt failure it could also be one of the hydraulic tappets that would receive the force of impact as it looks like the inside section where the valve makes contact.
The valve cap is a very substantial component,
Another place worth checking is the spring retaining tube for want of a better word as one part looks like 1 of the 2 lugs that keep the injector spring in place, I will dig out my broken one to photograph tomorrow.

Looks like the inner section to me viewed from underneath.

Cheers
Keith.

hi keith.

Thanks for posting the pic & it does look like that, yes. Would it mean my engine has had cambelt failure then? The guy was still running it & when I picked it up was still running albeit it roughly. Attached the pic below.

Cheers mate. Just ordered the cam locking kit & will start disassembling to investigate further.
