Re: 22nd and 23rd Series Suffix information
Posted by HH56 On 2023/9/9 12:49:13
The H suffix was apparently officially designated for use with 24th series engines coming from the factory with optional hydraulic lifers.
Cannot remember which year or specific subject covered but as I recall there is an article mentioning that the optional lifters may be found or maybe they could be dealer installed in other year engines. Don't remember specifics but as an aside to the subject of the article it suggested mechanics be sure to stamp an H on any engine that normally would not have had hydraulic lifters but mechanic had found or maybe installed them.
There have been some 22-23 series with an H suffix found and have been asked about on various forums.
