my 242 turbo has been on the lift for 3+ years if that makes it any better

Well, atleast you have a lift and a garage

This is true I'm attempting to downsize my stockpile/ fleet quite considerably so I can start work on my turbo 242, I'm very ADHD so easily distracted with new projects, but doing the maths on it realise I'm selling my time very cheap

The transmission sump on the 740 was leaking like a sieve. I knew when I put the thing together that I'd fecked up the threads.

Quick trip to home depot, to get the m10x1.5 bolt, a copper crush washer and fingers crossed we'll be set for a while.

I chased the hole out with a tap and greased up the channels to capture any swarf for good measure.

Then I took the zombie lights from the 249 rack and threw them onto the Yakima rack. A bit of angle aluminium I picked up off the side of the street, drill a few holes and some fresh stainless bolts, washers and nuts.

Loving the fleet. I'm wondering where you find all those 242s Austin and down there? Or just everywhere?

Facebook marketplace is a dangerous place.


Sold this one in a day and bought its replacement the same day

Anyways back to usual business, time for the 740's inspection shakedown, everything works, everything leaks, standard Volvo redblock experience lol.

She's running well, still have to:

Put on the rear overload springs,
Ipd sways
Boost gauge
Do something about leaking rack!

She's going through all the gears, have boost waaay low until I get a gauge on it but it's driving grand for the most part

Woah, your rack is leaking too? Let me know what you wind up doing about that. Looks great though!

I'll probably order a repro and fit it eventually, it's not so bad that it's even annoying at this stage thankfully

FML, hopefully broken timing gear but it does spin the top end with a breaker bar so we'll see this weekend, hopefully a quick fix!

 

[atomicdeathmonkey]

So this looks interesting, the question is what caused it, tension isn't great. Tear down of timing cover etc to follow.

 

[atomicdeathmonkey]

So I found these little bits of hard mud in the lower timing cover,, current theory? Mud daubers got in, made a nest and the belt slipped?

 

[atomicdeathmonkey]

And I was wrong

Decided to check the camshaft and the valves and noticed cylinder 1 valve lifter 2 not moving, on further investigation twas seized. Some cleaning up to do, on edge of the bore and a fresh lifter , hopefully

 

[atomicdeathmonkey]

Think it's working now, new lifter on the way and I'll throw it back together

Just skimmed through this whole thread. If I learned anything, it's that you take great care of your cars, and you have no self control (especially when it comes to wheels)

 

[rallydallas]

Wow never seen a Volvo lifter do that. Why is there a burned spot in the middle or what is that exactly? Just from the cam wearing on it?

Lol yes I've recently started offloading wheels mind !

That's the lifter without the shim on it , the little recess is filled with oil and looks burnt as a result.

Thought I'd found all the damage, sheared the pin on the camshaft gear too.


Still going with the obstructed timing belt theory, sudden stop threw a shim into the head ? It's bloody weird but I guess it's possible.


We'll see if it sounds like a bag of nails on startup.

Ahh, yeah, makes sense; I didn't notice the tappet cap was off.
