Valve lash specs needed

[Colin]

My Sambar is in desperate need of a valve adjustment... who's got the specs? Thanks!

Colin

Colin,
why don't you try the site I posted earlier today. See if they're as good and helpful as ther're advertising to be. Can't hurt can it?

www.subicbayminitrucks.com

[Colin]

Their "resources" section is down... sent them email requesting the information.

To clarify, this is a KS4 660cc engine. :)

[Colin]

I've been in touch with Tim from Subic Bay - he's hard at work translating manuals and updating their webpage. From the sounds of it, his contact in Japan has not yet replied with the lash spec.

Still looking for the info.

Colin:
How many kms are on your truck now? How do you know it "is in desperate need of a valve adjustment"?? What are the symptoms? Just curious.

I screwed with the adjustment when I was replacing the valve cover gasket. It sounds like gravel in a blender. :o

It seemed to need some adjustment beforehand, since it had a little rattle at certain RPMs.

Colin, have you checked what the valve clearances are right now? I do not know what the valve specs are on a Subaru,but I can give you the specs for a Suzuki F6A 660cc engine that might give you a reference at least.Cold engine, .003 intake,.006 exhaust

[Dan]

The mitsu's spec at ; .006" in .009" ex (cold) and .008"in and .012"ex (hot)

[Colin]

Thanks, guys. I'll split the difference and shoot for something around .007 on the intake and .009 exhaust... we'll see what happens. :D

[Colin]

Apparently, Tim at Subic Bay replied to me on the 11th, but I accidentally deleted the email. D'oh! :o

Valve lash - Subaru KS4
Cold setting

Intake .15mm +/- .02mm (.0059 in +/- .0007 in)
Exhaust .20mm +/- .02mm (.0078 in +/- .0007 in)

Many thanks to Tim at Subic Bay Minitrucks! :D

[zbadboy]

Colin glad you got that info. Big difference from the Mitsu and Suzi.

Bad news. I set the exhaust valves to .008 and intake to .006 today, the clicking noise decreased but was still present. On my way home I lost power and the engine started making a LOT of noise, then felt like it was running on two cylinders. I believe I've either blown a rod or popped a headgasket. :(

Time for that engine swap I've been talking about, I guess.

Colin

[BLES]

Oh, man! That's awful!:( I know us gearheads always like to think we "just had to" do that engine swap (or whatever project), but this is extreme! I don't want to think about tearing into one of these... no manuals/specs, no easy parts source...
Please document everything well.... maybe you'll end up with your own ENGLISH shop manual by the time you're done.
Keep us posted.

Actually, it sounds like you sucked a valve. Still VERY bad news.

[Colin]

Aye. Could be. :sly:

I took the day off at my part-time night job, so I'll probably pull the box off the truck and dig into the engine this evening.

Colin

[Wolfman]

Did you get the chance to pull the head? What did it look like inside? Care to post pics for the hardcore geeks like me? :D

[Colin]

You bet your *** I'll be posting pictures. :D

I'm going to pull the bed to facilitate engine swappage. Haven't quite got it off yet.

Colin

[hamradio]

when the swapping is in progress, might I drive over and see it for myself?

can't wait for pics.

[Colin]

Finally started swapping the engine today. I've been tied up with dozens of other projects recently.

I got the old engine out, thought about hefting the new one in place, and remembered my throwout bearing had been growling a little. Called up Joe at G&R Imports again and ordered a new throwout bearing and pilot bearing. Should be here early next week, then I can put the truck back together.

Look at the size of these intake ports!

I'm thinking one of the old pistons will be just about the perfect size for a shift knob (but not for the Sambar, since it has the 4WD button.) :D

Colin

[Timetripper]

Nice pics. What tires are you running in the pics?

[hamradio]

cool! could I come over and see it, sometime?

I s'pose you could... there's not much to see, though. :sly:

Colin, just rebuilding an SC. lost a rod and then customer kept running it to limp it home. rod broke at wrist pin end and then bashed around in the bore until it broke at the crank end and fell into the pan. started and ran on 3 cylinders to get him home. while runnung home the piston rotated in the bore and bent the valves and cracked the guides, Oh boy what a mess, massive damage but did not punch through the side of the block. Block was toast from cly bore damage. Just assembling again with replacement block, SC head out of the states and going good so far. just on here checking valve lash specs. Anyone got head bolt torque? I am at 25 ft/lb right now but I think they could be a touch more to get the correct bolt load.

[Colin]

Yikes! :eek:

My timing belt broke a few months ago and the truck has been sitting in the driveway. The court ruled that it wasn't a Class II ATV, so I can't drive it anywhere anyway. I'll fix it one of these days, I guess. :rolleyes:

Colin

[larryb]

yikes. do you want to sell it. i live in sauks rapids mn. call 320 2670005

[Colin]

Yeah... I think I might be about ready to part with it. Breaks my heart, but I really don't have the time or energy to overhaul it to the extent where it could be registered as a kit car and driven on the streets. :(

Colin
(320) 333-7880

[Colin]

I think I may be having a change of heart (already. :rolleyes: )

I rolled the truck down the hill and into the shop, pulled the belt cover off and discovered that the timing belt had indeed been destroyed, as I suspected. Replaced the belt, water pump, pullies, and tensioner with the stuff from my old engine (it looks like it's in better condition...)

Runs pretty well now, but the clutch is really starting to slip. I should've replaced that when I swapped the engine. D'oh!

Larry - call Nate (screen name: nateisanas) at (320) 309-2260 - he's been trying to sell his mid/late-80s Sambar with a custom extended cab. It's a 550cc twin, but despite that it seems to make at least as much power as my 660. We raced on 2nd street a few months ago and he started walking on me after 40 MPH or so. :D

Great success! :D

Woot woot! Colin lives! :D

Colin, was the picutres of the rusty gears on your replaced engine or your new/used installed engine. That does not look good. are your little rubber fillers installed between the upper and lower timming belt covers, looks like it has had a lot of water road grime entry, Or have you been swimming in the truck?
found torque for head bolts 3 kg m crosses over to 22-23 ft/lbs. I went 25 so should be good.
what was the failure on your old engine and is a ENO7 block? is crank, block, connecting rods still good?

[Colin]

I didn't take apart the old block yet - I just harvested the pulleys and stuff from it.

The rusty pulleys and water pump are on the replacement engine. I don't recall if the little rubber seals were in place on that block, though I did notice they were installed on the old block. I didn't reinstall them... maybe I should.

Hey all - has anyone ever verify that the valve lash specs were correct? Intake .15mm +/- .02mm (.0059 in +/- .0007 in) Exhaust .20mm +/- .02mm (.0078 in +/- .0007 in)
I put sythetic oil in mine and need to replace the valve stem guides (who would have thought something like that would cause such a problem). Smokes like a misquito fogger when cold now. Would hate to suck a valve like Collin. Plan to measure the lash before I pull the head, but would love to know the official spec. I cannot imagine that that an incorrect valve lash setting was the cause of the sucked valve in the thread???

... pulled the belt cover off and discovered that the timing belt had indeed been destroyed, as I suspected. Replaced the belt, water pump, pullies, and tensioner with the stuff from my old engine (it looks like it's in better condition...)

Runs pretty well now,

This suggests these are NON interference engines. Can anyone confirm that?
