Pre-war engine?

[thescifiguy]

I recently discovered that my '72 GT's engine has an oil pan from a 60's Kadette. So now I'm trying to figure out what year the block was made. I've read the various threads and it's supposed to be on the block near the starter. All that's there is "33" and "2a". January 2, 1933? The engine # is *19S-0344547*. That side of the engine also says 19 ; Opel ; and EB. So I seem to have one of the pre-'72 1.9L high compression engines. I haven't peeked at the pistons to see if they're flat-topped, but the engine certainly has that high compression pop-pop-pop note to the exhaust.

So, do I have a 1930's-era engine?

19s means its a 1900 CIH engine.

They were first produced in 1968. Everything else was either smaller or OHV.

The dipstick may be in the back of the pan on the opposite side by the oil pressure sending unit-that would be a 68-9 pan. Will have small loop style handle-wonder why they moved them, try to get to it in the car-well on a GT it would be tough

I 100% agree with you. When I first read this I couldn't believe mt eyes

Dumheit muss bestraft werden ("Stupidity deserves punishment" or something like that. My mom's favorite quote.) Pardon the spelling is it's wrong.

My apologies to anyone who was offended by my mild attempt at humor.

Yes, the dipstick is short, folded over, and located near the oil pressure sender. The year on the engine wouldn't be underneath or behind the starter would it? Are there dates also on the cylinder heads somewhere(in case that's been changed also)? What sorts of specifications would be different on this engine that were changed in later years?

The head date is cast into the head but you'll have to remove the valve cover to see it.

The history of the development of the Opel CIH engine, 1966-1993.

The motor type was designed in the early 1960's. Opel's Camshaft In Head engines were introduced in 1966 with the Opel Rekord B and Kadett B, soon finding their way into Rekord C, Opel GT, Opel Olympia A, Manta A and Ascona A. With this new engine Opel began a new era within motorsport, which started well with the Swede Lillebror Nasinius' championship win in the Eruopean Touring Car Rally of 1966, driving a 1900 Rekord B.

The CIH motors were initially available as 4-cylinder 1.5 - 1.7 or 1.9 litres, or the 6-cylinder engine available as 2.2 litres in the Rekord C for a very short period of time, and then were available as 2.5 and 2.8 in the Commodore A, Kapitän and Admiral. When the Rekord C Sprint was marketed in 1967 a sporty version of the 19s engine featuring 2 vertical Weber DFO carburettors were put into production, and the engine was also fitted to some Kadett B's for the foreign market. (hmmm - I wonder about this ... source may be confusing it with the dual carb 1.1L motor??)

Hardly Pre-War ... unless you are talking about the 1st Gulf war ...

Date codes on Opel castings are a little hard to decipher since we have so little information from the factory - but there are a pair of numbers cast on most heads that do indicated year of casting (and, perhaps on cylinder blocks also). Finding anything before 1965 ( or '65') would be a surprise though!

All the German maintenance manuals I've seen say the 'sprint' option was ONLY!! offered in all models of the Rekord C . . . unless you're counting the two Kadett B Coupés currently under construction here in the States . . . !

I also believed that the Rekord Sprint engine was designated as a 1.9H engine
May be mixing it up with a 1.9H head. I will have to look, or Otto may recall on that.

. . . in a word, CORRECT! 19H-heads, actually 19HL-heads, were cast with revised combustion chambers (9.5 CR) and special intake valve springs with 'closed' pressure raised by 5kp (33-38) and 'open' pressure raised by 9kp (57-66). 19HL-head cam specs, valve sizes and exhaust valve springs were identical to those used in the 19S engines.

[thescifiguy]

Okay, so where would I look on the head to find the 1.9S or 1.9H? Would that also be under the valve cover somewhere? Whereabouts would the casting date and other ID be under there?

This engine is the most ferocious sounding 1.9 GT engine I've ever owned. I've had 3 previous 9:1 compression engines and a 2L big valve and this baby sounds a lot like the latter.

Also, on the driver's side of the engine, there's a nickel-sized round plug or emblem near the timing chain cover that says: "Guaranty Void If Removed". Is this an indicator that the motor was rebuilt? The motor is painted baby blue if that's any help.

Crossing my fingers.....

When I was lapping in the valves on the 1.5 head that's now in my wagon, I noticed a hairline crack in the face of one exhaust valve. I tried one from a 1.9 and it did not fit. So I had to dig out another 1.5 head for the correct valve.

Correct . . . 1.5 head (38I/32E), unless modified, has smaller size valves than 1.9 (40I/34E) . . . 2mm is BIG difference!

19HL head uses same size valves as 19S head though . . . as I said.

Oops. I need to get some glasses. Sprint.. '68.. my brain registered that post as being about a 1.5 head.

There are two types of engines: N and S
