Introduced in the early 1970s as the largest member of Holden&#8217;s famous Red Motor family, the 202 quickly became the performance six-cylinder of choice for Kingswoods, Toranas, Premiers and commercial vehicles. It delivered strong low-down torque, simple maintenance and impressive durability, earning a reputation as one of Holden&#8217;s toughest powerplants.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even today, the 202 remains popular among enthusiasts thanks to its simplicity, abundant parts availability and strong aftermarket support. However, like any engine now approaching 50 years old, the 202 has several well-known weaknesses that owners and buyers should understand.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide explores the most common Holden 202 engine problems, their causes, warning signs and the best products to help keep these classic Australian sixes running reliably.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Understanding the Holden 202<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The 202 cubic inch (3.3-litre) six-cylinder engine evolved from Holden&#8217;s earlier Grey and Red Motor designs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Key Specifications<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Capacity: 202 cubic inches (3.3 litres)<\/li>\n\n\n\n<li>Inline six-cylinder configuration<\/li>\n\n\n\n<li>Cast iron block<\/li>\n\n\n\n<li>Cast iron cylinder head<\/li>\n\n\n\n<li>Pushrod valve train<\/li>\n\n\n\n<li>Carburettor fuel delivery<\/li>\n\n\n\n<li>Seven main bearing crankshaft<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The 202 was designed to be durable and easy to service, but decades of wear now expose several recurring issues.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Excessive Oil Leaks<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Oil leaks are arguably the most common complaint among Holden 202 owners.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Oil spots on the driveway<\/li>\n\n\n\n<li>Burning oil smell<\/li>\n\n\n\n<li>Oil residue underneath engine<\/li>\n\n\n\n<li>Constant need for oil top-ups<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Common Leak Points<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Rocker cover gasket<\/li>\n\n\n\n<li>Side plate cover gasket<\/li>\n\n\n\n<li>Timing cover seal<\/li>\n\n\n\n<li>Rear main seal<\/li>\n\n\n\n<li>Sump gasket<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The original cork gaskets used throughout the engine become brittle with age and eventually lose their sealing ability.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Best Rocker Cover Gasket Upgrade<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">Recommended Product: Permaseal Rocker Cover Gasket Set<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Benefits<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Improved sealing performance<\/li>\n\n\n\n<li>Better heat resistance<\/li>\n\n\n\n<li>Direct replacement fitment<\/li>\n\n\n\n<li>Reduced oil seepage<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Best For<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Routine maintenance<\/li>\n\n\n\n<li>Engine rebuilds<\/li>\n\n\n\n<li>Leak prevention<\/li>\n<\/ul>\n\n\n<div id=\"fu_ebay_0\"><!-- Presentation: cols = 4, rows = 2, slideshow = Manual, slides = 3, slideId = 0 --><div class=\"fu_ebay_results_container \">\n<h5 class=\"fu_ebay_results_title\" style=\"display: block !important;\">\n<a name=\"fu_slidetop_0\"><\/a><a href=\"https:\/\/www.ebay.com.au\/?mkcid=1&#038;mkrid=705-53470-19255-0&#038;siteid=15&#038;campid=5339152561&#038;customid=5339151688&#038;toolid=10049&#038;mkevt=1\" class=\"fu_ebay\" style=\"display:inline !important;\" rel=\"nofollow\" target=\"_blank\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/australianholden.com\/wp-content\/plugins\/fast-ebay-listings\/US\/Right_Now_108x45.gif?resize=108%2C45&#038;ssl=1\" style=\"border:0;display:block !important;\" width=\"108\" height=\"45\" alt=\"Right Now on eBay\"\/><\/a>&nbsp;Gasket<\/h5>\nLoading&#8230;<\/div>\n<\/div>\n<script>\n<!--\nvar content_fu_ebay_0 = null;\nvar waitForDepends_fu_ebay_0 = setInterval(function () {\n  if (typeof jQuery !== \"undefined\") {\n  if (window.fu_is_bot_useragent !== undefined) {\n    clearInterval(waitForDepends_fu_ebay_0);\n    if (typeof jQuery.ajax == \"undefined\") {\n      console.log(\"Fast eBay Listings: jQuery.ajax missing.

It powered countless Holdens through the 1970s and continues to enjoy strong support among enthusiasts, restorers and street machine builders.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its reputation for durability is well deserved, but age has introduced a range of predictable issues including oil leaks, timing chain wear, cooling problems and ignition faults. Fortunately, virtually all of these problems are straightforward to diagnose and repair.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With sensible maintenance, quality replacement parts and a few carefully chosen upgrades, a Holden 202 can still provide decades of reliable service. For many enthusiasts, the unmistakable sound and character of a healthy 202 is a reminder of why these engines remain so beloved in Australian motoring culture.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related Articles<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/holden-red-motor-cooling-system-problems\/\" type=\"post\" id=\"7234\">Holden Red Motor Cooling System Problems<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/20\/holden-red-engine-oil-leak-guide-2\/\" type=\"post\" id=\"7247\">Holden Red Motor Oil Leak Guide<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/17\/eh-holden-transmission-problems\/\" type=\"post\" id=\"7238\">EH Holden Transmission Problems<\/a><\/li>\n\n\n\n<li>Best Oils for Early Holden Engines<\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/20\/holden-186-engine-issues-explained\/\" type=\"post\" id=\"7268\">Holden 186 Engine Issues Explained<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/australianholden.com\/index.php\/2026\/06\/20\/powerglide-trimatic-issues-explained\/\" type=\"post\" id=\"7309\">Powerglide &amp; Trimatic Issues Explained<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Few engines are more recognisable in Australian motoring history than the Holden 202.
