Engine Age????

[dannyd]

How do you know the age of the engine (when was built, for what car, etc) ????

Reason i ask :
I got a nice deal on a H22A4, and the guy who i bought it from doesn't know anything of the engine.

thanks.

The only thing you can be certain of is that it came from a 97-01 Prelude in the US. You can tear it down and check its condition and maybe estimate its mileage, but that's about it. You can't determine its exact mileage or age (unless you know something about half-life).

does it have the vin tag on the lower front of the transmission or the back of the block? you could carfax that. otherwise youre out of luck.

the dude had it for almost a year, and he didn't have any records from the previous owner. I will do a complete tune up and leaks test.

I am going to Richmond in the summer, i have some family down there. Chester county.

thanks

Good idea. You might want to take off the valve cover too to see if there's any buildup of sludge.

What part of Chesterfield?

Model year encoding

One consistent element of the VIS is the 10th digit, which is required (in North America) to encode the model year of the vehicle. Besides the three letters that are not allowed in the VIN itself (I, O and Q), the letters U and Z and the digit 0 are not used for the model year code. Note that the year code is the model year for the vehicle.

The year 1980 was encoded by some manufacturers, especially General Motors and Chrysler, as "A" (since the 17-digit VIN wasn't mandatory until 1981, and the "A" or zero was in the manufacturer's pre-1981 placement in the VIN), yet Ford and AMC still used a zero for 1980. Subsequent years increment through the allowed letters, so that "Y" represents the year 2000. 2001 through 2009 are encoded as the digits 1 through 9, and subsequent years are encoded as "A", "B", "C", etc.
Code Year Code Year Code Year Code Year
A = 1980 L = 1990 Y = 2000 A = 2010
B = 1981 M = 1991 1 = 2001 B = 2011
C = 1982 N = 1992 2 = 2002 C = 2012
D = 1983 P = 1993 3 = 2003 D = 2013
E = 1984 R = 1994 4 = 2004 E = 2014
F = 1985 S = 1995 5 = 2005 F = 2015
G = 1986 T = 1996 6 = 2006 G = 2016
H = 1987 V = 1997 7 = 2007 H = 2017
J = 1988 W = 1998 8 = 2008 J = 2018
K = 1989 X = 1999 9 = 2009 K = 2019

What about the clock marks on the head? Anyone know how to read those?

you know i was just going to suggest those too.. it's been a while but i used to be able to read those.

well i know for an h22a, the engine is stamped with a circle and the year it was made inside. ie. (9|5) for 1995
