 |
|
Trying to rebound after an engine lock up from oil starvation (short story) lol. Have not pulled the engine but started looking around for possibilities in the worst-case scenario, because I am thinking there is no hope for an engine being ran with no oil bearings being stuck to the case etc. As of right now it's just fingers cross hoping for the best. I found an old case from my 67 back in the day. I pulled the cylinders an found these markings on the pistons and was wondering has anyone seen these marks and what do they mean? .

It is common to mark cylinder number on the top of pistons if they are to be removed.

Sorry, if I was not making myself clear those little //////// don't know if that area is called the piston skirts. I thought that area was all smooth from the ones I have seen.

| If you are talking about the knurling on the skirts, they have been knurled. When a piston gets worn, but the ring lands are OK we used to send them out to be knurled. It increased the diameter so the pistons didn't rock and slap in the bores. Never did it to a VW though. |

Doesn't really matter since I doubt you'll be reusing them.

Knowledge is key! It's all a learning experience to me, so moving forward is there anything or other stamps that I should be looking for on any reuseable parts. Like I said in the beginning I am here because My engine is locked up so when I get to take it apart, I will have some idea of what's reuseable or not. Next on the list is taking the engine out the car

I found an engine that has these numbers stamped on it 8998257 that tell me it's a 1200cc 40HP per Eng Code look-up. I took a scope to look at the cylinder walls to see if there was any damage done while looking around, I noticed stamped on the pistons 82.95. So, question is Eng still a 1200cc or is it a 1500cc? I read that 1500cc engines have a H code, but this engine doesn't. I am confused please help me understand what engine I do have.

Part number 113101371B '62-'64 40hp heads, plus 83mm piston/cylinders, means that most likely you're looking at a 1385cc "Big Bore" 40 horse engine.

Thanks for clearing that up for me. I am wanting to run this engine in the car till I figure out the damage in the other engine... What top speed would I able to get out of this 1385 engine. It's gonna be a daily for me....

That depends on how well you can tune it, what elevation you live at, how hilly it is, how strong is the headwind you're bucking, how good (or bad) your car's aerodynamics are, rolling resistance......
For a rough estimate, figure on performance similar to a '66 Bug.

Well, I was running a stock 1970 1600cc dual relief and I thought it did pretty good in my 63 bug not that many hills little incline on ramps at the toll roads got 55 to 60 on flat. Don't know to much about turning just whatever I have learned from the Samba and my book

If you only got 55-60mph out of a stock '70 1600SP then ya got problems. Same engine in my '60 was good for over 80mph in flat Texas.

I just drove it around town never really got a chance to try running it strong, before I blew the oil filter rubber seal and locked up the engine. Any advice on tuning and on other things I should be doing before I install and after install of new engine to get the most out of it as she sits. I know the basics oil plugs valves timing and carb adjustment anything else

Wow that was easier than I thought for a rookie like me. Don't know the belt looks a little tight... If anyone see anything that was missed let me know

From the pic, the belt does look a little tight. There should be about 1/2" of deflection between the pullies.
The throttle cable tube should pass through the forward (clutch end) tin, not sit on top of it.
If you leave it like that, the engine is gonna fight you upon installation.

The engine is missing the small air deflector tins that fit to the rear of the cylinders and fasten to the rear flange of the cylinder tins. They'd look similar to these (Jeckler gallery):

Rome not sure of how these tins look installed. Do you or anyone else have a picture of those tins installed on an engine and can you point them out thank you so much

I found one from one of my engines. Click on the pic to see where the lower tins are mounted left and right of the crank pulley.
