How to know if the engine is rebuilt or not

I recently bought a '94 4RUNNER V6 SR5 192,000 miles. It runs great
and I did not find any problems with it so far after driving another
2000 miles.I checked with dealer and they said Head Gasket is replaced
on that sometime around 2000.

How do I know if the engine is rebuit or Original? How to identify?

I bought a K&N air filter recently and the install instructions says
the filer has to be soaked in engine oil first. Why?

TIA.

I have a friend with a 94 4runner and he has a cracked head. I hear that is
a common problem for those engines .
One way to see if the engine is rebuilt is to pull off the head and mic the
cylinder bore, if it was rebuilt it's probably bored .030 over.

K&N filters are a very bad idea in my opinion. The reason that they want you
to put oil in the filter is to catch the silca dust that the filter media is
unable to capture due to the fact that it allows larger particulates to pass
unlike normal disposable filters. Sure you may get more horsepower (just as
you would with NO filter) but you're gonna wear out your engine's components
faster with the particulate contaminates.

Only way to tell is to remove the head/s and measure the bores, or at least
carry out a compression test. K&N filters arent too bad but Id stay with
paper If I where you, need to replace more often but better at filtration.

If you do get a K&N unit buy there oil as its way better than engine oil.

Yabbut, the sticker gives you 2.3 HP!

Well, I guess I can not pull the head and inspect myself OR spend some
money to do so (I bought the 4runner for $2500) .

What is the typical life of original engine with head gasket replace by
toyota? is 200,000 miles too mouch and it must be a rebuilt engine?
What is the typical life of rebuilt engine as well?

TIA

If the V6 was rebuilt correctly and its been fully serviced with oil changes
each 3000mls it should last another 120,000miles easy.

My 4runner has 238,000kms on it so far and still the origional engine. Not
sure if its had the head gasket done or not. It certainly hasnt been
rebuilt.

Since you just bought the truck It doesn't really mater. The motor is most
likley the original with the head gaskets replaced, common problem. Being
that it is a toyota with proper care it should go 300 K miles maybe more

Thanks. I was just wondering what are the tell tale signs for a rebuilt
engine.

It drives OK and from what I can see in the engine compartment all the
parts are still original DENSO parts I think. Are the belts I see
outside, can I change myself? Does this '94 4runner SR5 V6 has timing
belt or chain?

Also, I hear clicking/ticking sound in front drive shafts I think, when
I engage H4 and turn tight corner. Can I replace them myself?

TIA

The fanbelts and such are easily user-replaceable. Grab a Haynes or Chilton
manual for simple stuff like that.

The V6 uses a timing belt. In theory, to be replaced every 60K miles, but since
it's a non-interference engine, you can roll the dice with no downside other
than a tow to the mechanic if the belt breaks.

My '99 says replace at 90,000 miles. We will replace the water pump and
hoses at the same time. Dealer price for belt replacement quoted at
$275.00 total. Not worth the inconvienence and expense of the tow for
that price.

Yeah, somewhere around the 1999/2000 model years, Toyota went to spec'ing a 90K
mile service interval on the timing belt. However, the OP is sporting a '94 V6,
thus a 60K interval. IMHO, the change from 60K to 90K was more of a
recognition that those belts are *tough* -- I've heard of a number of folks with
well over 100K on the original belts on their mid-90's V6 motors. Personally,
I've got 82K on mine (a '96 Taco V6). Somewhere around 90K, I'll probably
mosey in and get 'er replaced. $275 is a decent price from a dealer -- I don't
think my local mechanic (who normally beats the dealer by a wide margin) could
beat that by much.

OTOH, when my 2002 Sequoia (a V8) hits 90K, you can bet I'll have that sucker at
the mechanic's mucho pronto -- I don't take chances with interference engines.
Still can't believe Toyota made an interference engine with a timing belt...

Honda did on their 70's era Civic. A Rural Health Nurse I know lost the
timing belt on her Civic doing 70mph. It locked up the engine and put
her in a skid until she was able to get the clutch disengaged.
She said it was a ride she didn't want to take again.

between 98 and 99 they changed the recommended intervals - I believe my 98
is supposed to be either 60 or 75 but in 99 they say 90 - this is for the
3.4. Anyway, I don't think belt technologies have changed between those years
and I think the part numbers are the ssame. They may errored on the side
of caution during the first few years of the 3.4 or something.
